Question
A cubical tank of side 1 m is filled with 800 kg of a liquid. Find:
(i) the volume of tank,
(ii) the density of liquid in kg m-3.

Solution
(i) Volume of a cube = side × side × side
side = 1 m
∴ volume = 1 m × 1 m × 1 m = 1 `m^3`
(ii) Density of liquid in kg `"m"^-3`
= `" mass (m) "/" volume (v)"`
Mass = 800 kg
Volume = 1 `"m" ^ 3`
∴ Density = `800/(1"m"^3)` kg = 800 kg `"m"^-3`
