A filled water bed has the dimensions 8.0 ft x 7.0 ft x 0.75 ft. Determine the mass of water, in kilograms, needed to fill the bed. Density of water = 1.00 g/cm^3.

Expert Solution

1ft = 30.48cm

volume = 8.0 ft x 7.0 ft x 0.75 ft.

= 8*30.48cm*7*30.48cm*0.75*30.48cm

= 243.84cm*213.36cm*22.86cm = 1189307.56cm³

mass of water = volume * density

= 1189307.56cm³ *1g/cm³

= 1189307.56g

= 1189.307Kg >>> answer
