A water bed has a dimension of 2m × 2m × 2m. The floor of the bed will tolerate an additional load of no more than 600N. Find the weight of the bed and determine whether it should be purchased.

Physics 
Henry,
Vw = 2 * 2 * 2 = 8 M^3 = 8*10^6 cm^3. =
Vol. of the water.
Dw = 1g / cm^3 = 0.001kg / cm^3. = Density of water.
Mass = Vw * Dw.
Mass = 8*10^6cm^3 * 10^3kg/cm^3 = 8*10^3kg = 8000 kg. = Mass of water.
Wt. = mg = 8000kg * 9.8N/kg = 78,400 N.
= Wt of water.
