density of A: 1.2kg/(20*10*5)cm^3 = 1.2/1000 = 0.0012 kg/cm^3 = 1.2 g/cm^3
Block B is 6cm on a side, with a density of 1.2*1.4 = 1.68 g/cm^3
So, its mass is
1.68 g/cm^3 * 216cm^3 = 362.88 g = 0.36 kg
Plastic block A has a mass of 1.2kg. Plastic block B is made from plastic with a density 40% greater than the plastic block. Work out the mass of the plastic cube. Plastic block A is 20cm by 10cm by by 5cm. Cube is 6cm. Is it
6×6×6=216
216 ×1.4
