It can support a mass M such that
M + m = volume x (water density)
where m is the mass of the mattress and Volume = 0.1 m^3. The water density is 1000 kg/m^2.
Solve for M
M + m = volume x (water density)
where m is the mass of the mattress and Volume = 0.1 m^3. The water density is 1000 kg/m^2.
Solve for M
