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.

Answer 1

Check the size of a water bad!
Is it really 2m x 2m x 2m?
If so, then
V=2• 2• 2 = 8 m^2 !!!!!!!!!!!!!
Density of water is D = 1000 kg/m^3, then
mg = DVg=1000• 8• 9.8=78400 N
