CBSE Class 5 Mathematics How Heavy How Light Worksheet Set 02

Question 1. Find the volume of the rectangular prism with length = 8 m, width = 3 m, and height = 4 m.
Answer: Formula for volume of a cuboid = length \(\times\) width \(\times\) height
Length = 8 m = 800 cm
Width = 3 m = 300 cm
Height = 4 m = 400 cm
Volume = \(800 \text{ cm} \times 300 \text{ cm} \times 400 \text{ cm} = 96,000,000 \text{ cm}^3\)
In simple words: Convert the dimensions from meters to centimeters and multiply length, width, and height to find the volume in cubic centimeters.
Exam Tip: Always make sure all dimensions are in the requested unit before calculating the final volume.

Question 2. Find the volume of the cube with side = 3 cm.
Answer: Formula for volume of a cube = \(\text{side} \times \text{side} \times \text{side}\)
Volume = \(3 \text{ cm} \times 3 \text{ cm} \times 3 \text{ cm} = 27 \text{ cm}^3\)
In simple words: Multiply the side length by itself three times.

Exam Tip: A cube has equal length, width, and height.

Question 3. Find the volume of the rectangular prism with length = 15 cm, width = 4 cm, and height = 8 cm.
Answer: Formula for volume of a cuboid = length \(\times\) width \(\times\) height
Volume = \(15 \text{ cm} \times 4 \text{ cm} \times 8 \text{ cm}\)
\(15 \times 4 = 60\)
\(60 \times 8 = 480 \text{ cm}^3\)
In simple words: Multiply the three given dimensions together to get the total volume.

Exam Tip: Double-check your multiplication steps to avoid calculation errors.

Question 4. Find the volume of the cube with side = 6 cm.
Answer: Formula for volume of a cube = \(\text{side} \times \text{side} \times \text{side}\)
Volume = \(6 \text{ cm} \times 6 \text{ cm} \times 6 \text{ cm}\)
\(6 \times 6 = 36\)
\(36 \times 6 = 216 \text{ cm}^3\)
In simple words: Cube the side length by multiplying 6 by itself three times.

Exam Tip: Remember to write the unit as cubic centimeters or \(\text{cm}^3\).
