V = volume

SG = specific gravity

W = weight

V = 5m

^{3}SG = 1.5

**First we need to find the specific weight. Then we multiply that result by the volume.**

γ = ρg

where:

ρ = density

g = 9.81 m/s

^{2}ρ = SG * 1000 kg/m

^{3}ρ = 1.5 *1000 kg/m

^{3}ρ =1500 kg/m

^{3}**Plug this into**γ.

γ = ρg

γ = (1500 kg/m

^{3}) (9.81 m/s^{2})γ = 14715 kg/m

^{2}s^{2}W = γ V

W = (14715 kg/m

^{2}s^{2})(5 m^{3})W = 73575 kg m /s

^{2}These are the steps you will take.
