The pentagonal pyramid comes up quite often during elementary math when the next level of difficulty is added after the square pyramid.
Just the challenge of finding the area of the pentagon alone, is enough to confuse some kids - so don't let this be your child's story. There is nothing more or less complicated about a pentagon than the square or triangle, other than calculating its base area.
This however in general will actually be supplied for the elementary student.

Base Shape | |
Faces |
SIX - The five side faces are triangles and the base shape is a pentagon. |
Vertices |
6 Vertices |
Edges |
10 Edges |
Surface Area |
Where: t = lateral height; P = Perimeter of Base; B = Area of Base |
Volume |
B = Area of Base; h = Perpendicular Height |
Area of Pentagon |
Your student is not expected to know or use this formula, I have put it here for interest purposes only. If your child is expected to find the area of a pentagon, it will be by calculating the area of triangles, when they are given the value of the Apothem.
