Hi, I'm calculating the work done by regular tetrahedron during taking from the water by crane (USING INTEGRALS). I don't know how bad is that solved so if anyone checks my work and gives me some advice or hints I would be very glad.

Everything is written in the PDF file.

There were given:

Tetrahedron side - "a";

Water depth - "L";

The density of iron (tetrahedron material) - "rho (Fe)".

I assumed the density of water and the pulling force of the crane.

Also, I divide the problem into two parts, the first is the work done before it came out from the water, and the second one is starting to come out from it.
