Question

The dimension of wooden block are 2mX0. 25mX0. 1m. One of the relative density of wood is 0. 6, calculate the mass of the block in kg. Density of water is 10X10X10 kg /mcube

Answer 1

Volume of block = 0.25 * 2 * 0.1 = 0.05 m^3 or 500 cm^3
if relative density is 0.6, density is 0.6 g cm^-3
d = m/V
m = dV
= 0.6 * 500
= 300 g
= 0.3 kg
