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

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.

so,

26*3.9*23*(1.0*10^3)-3.5=2332196.5
