Hi!
Styrofoam has a density of 32 kg/m^3
Per cubic meter of lake water, there are 1000 kilograms of water
Weight + mass of ice = BuoyantForce
Physics problem
The *water*V*g is equal to the ρice*V*g
so V(*water – *ice) = m
( *water -*ice) / m
This implies that V = 34 / 1000 – 32 = .0351 m^3
Hope this helps! Best wishes! Different density grades can float between 48 and 55 pounds. You can build your own boat from only the can foam/cardboard frame when you were younger me and my friend built a 6 foot boat from only the can foam/card board frame made a 6 foot boat like thing took 10 cans that’s like $23 or so.
