A rectangular solid is 5m long, 2m high and 4m wide. The mass of the solid is 300g. Find the density of this solid.​
Over [174]

Answer:

Density = Mass / Volume

Mass = .3 kg

Volume = 2 * 5 * 4 = 40 m^3

Density = .3 g / 40 m^3 = .0075 kg / m^3

1 kg/m^3 = kg * 1000 g / kg / (1 m^3 * (100 cm/m)^3) = 10E-3  gm/cm^3

Density = 7.5 E-3 gm/cm^3
