The bouyancy is equal to volume*densitywater(g).
Supported Weight=bouyancy-weightmat
mg=volume*density*g-3.5kg
masssupported=volume*densiy -3.5kg
where density is the density of water.
a 3.5 kg rectangular air mattress is 2.73m long, 1.1m wide, and .124m thick.
what mass can it support in water befor sinking?
answer in units of kg.
so do i do volume times density=mass?
3.5*2.73*1.1*.124=1.303302

density of water=1.0*10^3
so,
26*3.9*23*(1.0*10^3)-3.5=2332196.5
so,
26*3.9*23*(1.0*10^3)-3.5=2332196.5
