Answer:
Side of cube= 4 m
Step-by-step explanation:
here,volume of cubical tank= 64,000 litres
In cubic metre the volume of water= 64,000 / 1000 cubic metre
[1000 litres = 1 cubic metre]
therefore, volume of tank in cubic metre= 64 cubic metre
now,let the side of cubical tank be X m
so, volume of cubical tank= side*side*side
64 metre cube= X*X*X M
64 metre cube= X^3 M
X= cube root 64 metre cube
X= 4 m
therefore, length of side of cubical tank is 4 m.
