PLEASE HELP A frustum of a regular square pyramid has bases with sides of lengths 6 and 10. The height of the frustum is 12.
Find the volume of the frustum?
Find the surface area of the frustum?

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
