Question

A storage tank in form of a cube has water up to its brim. The amount of water in the tank is 4096 m³. After some time, it is found that the depth of water present is 12 m. Find the volume of water used.

• A. 1024m³
• B. 848 $m^3$
• C. 1184 $m^3$
• D. 988 $m^3$

Answer 1

The correct option is A

1024m³

The storage tank is a cube of volume 4096 $m^3$.

Therefore the dimensions of the cube are 16 × 16 × 16

The present depth of water (h) is 12 m.

Therefore depth of water already used (h^I) = 16 -12 = 4 m

Therefore volume of water already used = (l x b x h^I) = 16 × 16 × 4 = 1024 $m^3$
