Question

Capacity of water tank is 1000 $l$. If the shape of tank is cube then find the side of the cube.

Answer 1

Capacity of water tank is 1000 $l$.

Volume of the tank = 1000 $l$

$=1000\times 1000$ cm${}^3$

= 1000000 cm${}^3$

Volume of the cube = a${}^3$

1000000 = a${}^3$

$\sqrt[3]{31000000}=\sqrt[3]{3a^3}$

$a=100$ cm

Hence, the side of the cube is 100 cm i.e. 1 m
