Answer 6

@Bram It's against the code of conduct of OS to give direct answers and help an individual cheat.

Answer 7

V = (1/3)b^2h where b = base length, h = height from vertex to the base
V = 13 b^3 because base and height are the same
Since the cube has volue of 81 m^3, then
b^3 = 81
b = 81^(1/3)
V = 13 ( 81^(1/3) )
V = (1/3)(81)
V = 27 m^3
