Question

Nexus made a solid with a cube and a cuboid. Calculate its combined volume.

• A. 109 cubic meters
• B. 110 cubic meters
• C. 111 cubic meters
• D. 112 cubic meters

Answer 1

The correct option is C 111 cubic meters

Total volume = Volume of cube + Volume of cuboid
Volume of cube
= Length $\times$ Width $\times$ Height

For a cube: length = width = height

$\therefore$ Volume of the cube = 3 $\times$ 3 $\times$ 3
= 27 cubic meters

Volume of the cuboid
= Length $\times$ Width $\times$ Height
= 4 $\times$3 $\times$ 7
= 84 cubic meters

Total volume = 27 + 84
= 111 cubic meters
