Question 33427
Volume of Cubeoid = x*y*z  where x,y and Z are the dimensions of cubeiod
Volume of cylinder : {{{(pi)*(r^2)*(h)}}}  where r = radii and h  =height

A square pyramid is a pyramid with a square base. It is a pentahedron.
Its volume is given as v = {{{(1/3)*(x^2)*h}}} where x = length of the side of square base and h = height of the pyramid

Substitute the values and solve the problems.Remember the units for volume are cubic units
