Question

Toby created a water tank for his pet. Find the volume of the tank.

• A. 86 cubic cm
• B. 90 cubic cm
• C. 94 cubic cm
• D. 96 cubic cm

Answer 1

The correct option is D 96 cubic cm

To find the volume, let's devide the figure into different solids.

Total volume = Volume of two cubes on the top + Volume of cuboid at bottom.

Volume of cube
= Length $\times$ Width $\times$ Height

For a cube: length = width = height

Volume of the cube
= 3 $\times$ 3 $\times$ 3 = 27 cubic cm

Volume of the cuboid
= Length $\times$ Width $\times$ Height
= 2 $\times$ 7 $\times$ 3
= 42 cubic cm

Total volume = 27 + 27 + 42
= 96 cubic cm
