Answer

Side = 1 m; mass = 800 kg

(i) Volume of cubical tank = (side)3 = (1 m)3 = 1 m3

So, volume of tank = 1 m3.

(ii) Density=MassVolumeDensity=8001=800kg m3\text{Density} = \dfrac{\text{Mass}}{\text{Volume}} \\[1em] \text{Density} = \dfrac{\text{800}}{\text{1}} = 800 \text{kg m}^{3}

So, density of liquid = 800 kg m-3.
