For a twin-sized air mattress used for camping has dimensions of 100 cm by 200 cm by 15 cm when blown up, the weight is mathematically given as

M=2923.38N

What is the weight of a person could the air mattress hold if it is placed in freshwater?

Generally, the equation for the maximum mass is mathematically given as

M=Vp-m

Therefore

M=100*200*15(1*10^3)-2kg

M=298kg

In conclusion, the weight

W=298kg*9.81

W=2923.38N
