This set of Mathematics Multiple Choice Questions & Answers (MCQs) focuses on “Mensuration – Volume of Cube, Cuboid and Cylinder”.

1. Find the volume of the given figure.

a) 2400 cm3
b) 1600 cm3
c) 2200 cm3
d) 1400 cm3

Explanation: Volume of a cuboid = l × b × h = 20 × 15 × 8 = 2400 cm3.

2. What is the volume of the given figure?

a) 2642 cm3
b) 2644 cm3
c) 2744 cm3
d) 2742 cm3

Explanation: Volume of cube = a3 = 143 = 2744 cm3

3. Find the capacity of the cylinder. (π = $$\frac{22}{7}$$)

a) 1366 m3
b) 1276 m3
c) 1376 m3
d) 1386 m3

Explanation: Volume of cylinder = πr2 h = $$\frac{22}{7}$$ × 72 × 9 = 1386 m3.

4. A cuboid box is having measurements 5m × 8m × 12m. How many cube boxes having side 2m can be kept inside the cuboid box?
a) 80
b) 120
c) 240
d) 60

Explanation: No. of cube boxes = $$\frac{Volume \,of\, cuboid\, box}{Volume\, of\, cube\, box} = \frac{l × b × h}{a^3} = \frac{5×8×12}{2^3}$$ = 60

5. A cylindrical tank is having height 6m and radius 4 m. How much litres of water can be filled in the tank? (π = 3.14)
a) 301.43
b) 301.46 m3
c) 301.44 m3
d) 301.45 m3

Explanation: Capacity of the tank = πr2 h = 3.14 × 42 × 6 = 301.44 m3.

6. A cuboid is having volume 3674.16 cm3. Find the unknown data.

a) 12.5 cm
b) 12.6 cm
c) 11.6 cm
d) 11.5 cm

Explanation: Volume of a cuboid = l × b × h
3674.16 = 16.2 × 18 × x
x = 12.6

7. Find the height of the cylinder whose volume is 14.08 m3 and radius is 4 m.
a) 0.54 m
b) 0.56 m
c) 0.14 m
d) 0.28 m

Explanation: Volume of cylinder = πr2 h
14.08 = $$\frac{22}{7}$$ × 42 × x
X = 0.28 m.

8. If the edge of a cube is doubled then how many times the volume will increase?
a) 1
b) 2
c) 4
d) 8

Explanation: Volume of cube = a3
If side is doubled,
Volume of cube = (2a)3 = 8a3.
