Question

The mass of an empty bucket of capacity 10 litres is one kg. Find its mass in kg when completely filled with the liquid of relatively density 0.8.

Answer 1

Density of liquid is $0.8\times {10}^{3}kg/m^3$

Volume of bucket is $1/100m^3$

So mass of liquid is density× volume = $0.8\times {10}^3\times 1/100=8kg$

Total mass = 8+1 = 9 kg.

Its mass will be 9 kg after filling with liquid.
