Question

• A. 190 cubic meters
• B. 176 cubic meters
• C. 189 cubic meters
• D. 200 cubic meters

Answer 1

The correct option is C 189 cubic meters

The total water the tanks can hold is equal to the sum of volumes of both the tanks.

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

For a cube: Length = Width = Height

Volume of the tank (with height 5 m)
= 5 $\times$ 5 $\times$ 5 = 125 cubic meters

Volume of the tank (with width 4 m)
= 4 $\times$ 4 $\times$ 4 = 64 cubic meters

Total volume = 125 + 64
= 189 cubic meters
