Volume of cubical tank = 15.625 cu. m
(Side)3 = 15.625 cu. m
Side = 2.5 m
Volume of water used = 2.5 × 2.5 × 1.2 = 7.5 cu. m
Volume of water left in tank = 15.625 - 7.5 = 8.125 cu. m
Required ratio = 7.5/8.125 = 12/13 = 12 : 13

Ans. Volume of cubical Tank = 15.625 m3
Let Side of cubical Tank = x m
Then,
{tex}=> x^3 = 15.625{/tex}
{tex}=> x = 2.5 m{/tex}
Present Deptj of water = 1.2 m
Present volume of water = {tex}2.5\times 2.5\times 1.2 = 7.5m^3{/tex}
Volume of water used = 15.625 - 7.5 = 8.125m3
Ratio = 8.125 : 7.5 = 13 : 12
