    If a cube was sunk into the ground so that...

    If a cube was sunk into the ground so that one of the 4 diagonals of the cube is perpendicular to the ground, similar to Cube Problems except the the cube is suck into the ground so the the cross section between the ground and cube is a hexagon. If the rays of the sun hit the ground at right angles, what shape is the shadow that it makes?

    Could you explain why the shadow would be a pentagon?

    I did not understand how it will be a pentagon. The rays hit the ground at right angles then how it will form a pentagon shape?
