What is the perimeter of a rectangle with a length of 5 units and a width of 3 units?
16 units
15 units
10 units
8 units
The perimeter of a rectangle is calculated using the formula P = 2 Ã- (length + width). Substituting 5 and 3 into the formula gives 2 Ã- (5 + 3) = 16 units.
Which is the smallest unit of length among the following?
Millimeter
Centimeter
Meter
Kilometer
A millimeter is one-thousandth of a meter and is the smallest unit listed. The other units are progressively larger in size.
Which unit is most commonly used to measure liquid volume?
Liter
Kilogram
Centimeter

Liquid volume is typically measured in liters, the standard metric unit for volume. The other options represent measurements of mass or length.
What is the area of a square with each side measuring 4 units?
8 square units
16 square units
12 square units
4 square units
The area of a square is calculated by squaring its side length, so 4 Ã- 4 equals 16 square units. This is a direct application of the area formula for squares.
How many meters are equal to 100 centimeters?
1 meter
1000 meters
0.1 meter
10 meters
Since 1 meter is defined as 100 centimeters, 100 centimeters is equivalent to 1 meter. This conversion is a key concept in the metric system.
What is the volume of a cylinder with a base radius of 3 cm and a height of 10 cm, using π = 3.14?
282.6 cubic centimeters
314 cubic centimeters
56.5 cubic centimeters
94.2 cubic centimeters
The volume of a cylinder is calculated using the formula V = Ï€ Ã- r² Ã- h. Substituting r = 3 cm and h = 10 cm gives V = 3.14 Ã- 9 Ã- 10 = 282.6 cubic centimeters.
How many centimeters are in 2.5 meters?
2.5 centimeters
25 centimeters
250 centimeters
2500 centimeters
Since 1 meter equals 100 centimeters, multiplying 2.5 by 100 gives 250 centimeters. This conversion reinforces the relationship between meters and centimeters.
If the length of a rectangle increases by 20% while the width remains unchanged, by what percentage does the area increase?
None of the above
20%
40%
10%
When the length increases by 20% and the width remains the same, the new area becomes 1.2 times the original area, which is a 20% increase. There is no compounding effect since only one dimension changes.
What is the area of a triangle with a base of 8 units and a height of 5 units?
40 square units
10 square units
13 square units
20 square units
The area of a triangle is found using the formula A = ½ Ã- base Ã- height. Substituting the given values results in ½ Ã- 8 Ã- 5 = 20 square units.
How many cubic centimeters are equivalent to 1 liter?
1,000,000 cubic centimeters
1000 cubic centimeters
10,000 cubic centimeters
100 cubic centimeters
In the metric system, 1 liter is by definition equal to 1000 cubic centimeters. This conversion is a fundamental concept in volume measurement.
If a rectangle has a perimeter of 24 units and its length is 1 unit longer than its width, what are the dimensions of the rectangle?
Width: 5 units, Length: 7 units
Width: 5.5 units, Length: 6.5 units
Width: 4 units, Length: 8 units
Width: 6 units, Length: 6 units
Let the width be w and the length be w + 1. The perimeter is given by 2 Ã- (w + (w + 1)) = 24, which simplifies to 4w + 2 = 24. Solving for w gives 5.5 and the length becomes 6.5.
What is the area of a circle with a radius of 7 units, using π = 3.14?
49 square units
154 square units
153.86 square units
21.98 square units
Using the formula A = Ï€ Ã- r², substituting r = 7 results in A = 3.14 Ã- 49, which equals approximately 153.86 square units. This calculation ensures proper use of the area formula for circles.
What is the volume of a rectangular prism with dimensions 5 cm, 4 cm, and 3 cm?
60 cubic centimeters
30 cubic centimeters
24 cubic centimeters
12 cubic centimeters
The volume of a rectangular prism is calculated by multiplying its length, width, and height. Here, 5 Ã- 4 Ã- 3 equals 60 cubic centimeters, making it the correct answer.
Convert 3.5 kilometers to meters.
3.5 meters
35,000 meters
3500 meters
350 meters
There are 1000 meters in 1 kilometer, so 3.5 kilometers is equal to 3.5 Ã- 1000, which equals 3500 meters. This conversion reinforces the metric system relationship.
If 1 inch equals 2.54 centimeters, what is the length in inches of an object that measures 25.4 centimeters?
2.54 inches
10 inches
25.4 inches
12 inches
Dividing 25.4 centimeters by 2.54 gives 10 inches. This is a standard conversion factor between inches and centimeters, confirming the correct answer.
A garden measures 15.3 meters by 10.7 meters. What is its area rounded to the nearest square meter?
165 square meters
163 square meters
162 square meters
164 square meters
Multiplying 15.3 meters by 10.7 meters yields approximately 163.71 square meters. When rounded to the nearest whole number, the area becomes 164 square meters.
A cylindrical water tank has a radius of 2.5 meters and a height of 8 meters. Using π = 3.14, what is its volume in cubic meters rounded to one decimal place?
150.0 cubic meters
157.0 cubic meters
160.0 cubic meters
155.5 cubic meters
The volume of a cylinder is given by V = Ï€ Ã- r² Ã- h. Substituting r = 2.5 and h = 8 results in V = 3.14 Ã- 6.25 Ã- 8, which computes to 157.0 cubic meters when rounded appropriately.
A picture frame has outer dimensions of 20 cm by 30 cm and an inner opening of 15 cm by 25 cm. What is the area of the frame's border?
825 square centimeters
225 square centimeters
375 square centimeters
600 square centimeters
The area of the border is calculated by subtracting the area of the inner opening from the area of the outer rectangle. With outer area 600 cm² and inner area 375 cm², the border area is 600 - 375 = 225 cm².
The dimensions of a rectangular prism are in the ratio 2:3:4 and its volume is 192 cubic centimeters. What is the length of the longest side?
8 centimeters
16 centimeters
6 centimeters
12 centimeters
Let the dimensions be 2x, 3x, and 4x. The volume is 24x³ = 192, which gives x³ = 8 and x = 2. Therefore, the longest side is 4x, which equals 8 centimeters.
A regular hexagon is divided into 6 equilateral triangles. If each side of the hexagon is 10 cm, what is the approximate area of the hexagon? (Area of one equilateral triangle ≈ 0.433 Ã- side²)
259.8 square centimeters
245 square centimeters
200 square centimeters
300 square centimeters
Each equilateral triangle has an area of approximately 0.433 Ã- 10² = 43.3 cm². Since the hexagon contains 6 such triangles, its total area is roughly 6 Ã- 43.3, which equals about 259.8 cm².

Measurement Practice Worksheets Cheat Sheet

  1. Know Your Length Units - Inches, feet, yards, and miles make up the customary system, while millimeters, centimeters, meters, and kilometers belong to the metric family. 1 foot equals 12 inches, and 1 meter equals 100 centimeters - knowing these staples will help you switch between systems like a measurement ninja.
  2. Measure Like a Pro - Always start your ruler or tape at zero, and line up your object carefully to avoid "ghost" measurements. Read to the nearest mark and note if you're estimating between lines.
  3. Convert with Confidence - Flip between inches and feet (12 inches = 1 foot) or centimeters and meters (100 centimeters = 1 meter) without breaking a sweat. Practice converting small to big units and vice versa to master the magic of scaling.
  4. Perimeter Power-Up - Perimeter is just the distance around a shape - add all the sides and you're done! For rectangles, P = 2 × (length + width), so grab your calculator or do it in your head.
  5. Awesome Area Adventures - Area measures the surface inside a shape, so multiply its length by its width: A = l × w. You'll end up with square units - picture tiny tiles covering your shape!
  6. Volume Victory - Volume tells you how much "stuff" fits inside a box - use V = l × w × h for rectangular prisms. Imagine filling the box with building blocks to see how volume really works!
  7. Weight Wizardry - In customary units you'll find ounces and pounds (16 oz = 1 lb), while grams and kilograms rule in metric (1,000 g = 1 kg). Practice by weighing snacks or classroom objects.
  8. Capacity Capers - Cups, pints, quarts, and gallons in the US system, and milliliters and liters in metric, measure how much a container can hold. Remember: 4 cups = 1 quart, and 1,000 mL = 1 L.
  9. Scale Detective - From rulers to bathroom scales to thermometers, every instrument has a scale you must read correctly. Watch for skip marks and decimals to get the most precise reading.
  10. Real-World Measurement Missions - Calculate the paint needed for a wall by using area, or find out how much water a tank holds with volume. Solving practical problems makes you the hero of your own math story!
