let the length of the edge of the cube be x. therefore
the volume of the water when the tank is full = the volume of the tank
x³=√15.625
x=³√15.625
x=2.5m
the area of the base of the tank = 2.5*2.5=6.25 sq m
present depth of the water is 1.3 m.
therefore present volume of the water = area of the base * depth
=6.25*1.3
=8.125 cubic m.
thus the volume of the used water = volume of the tank - present volume of the water
=15.625-8.125
=7.5 cubic m.
