prove that the maximum volume of a regular tetrahedron (prism with equilateral triangles faces) inscribed in a sphere of radius 5 cm is 125 cm^3. thanks in advance
im woking at math 2 the proplem is from applications on local maximum and minimum by using derivative of a function i have a good knowledge in solid geometry .if there is something wrong with the final volume just ignore it i want the procedures whatever the final answer is .
