isn't it just (t^5)/(6^6)?

*1 and 12 are incorrect it is 8 minutes

That is right 80+80=160 and (180-160)/2=10 degrees

I agree with geno

The surface area is pi*r(r+sqrt(r^2+h^2))so the surface area is 96pi

I feel like this is is an easy problem.

the square base has area 64 and then we use the Pythagorean theorem to solve for the height. 4sqrt3^2=h^2+4^2, so 48=h^2+16, and h^=32, or 4sqrt2. 4sqrt2*64/3, which is approximately 120.7 cubic feet.

You are right, that does work out.

y = (sqrt3/3)x
