How many triangular bases are there among three square pyramids and two pentagonal pyramids

2 answers

To determine the number of triangular bases among three square pyramids and two pentagonal pyramids, we need to find the number of triangular faces in each type of pyramid and then sum them up.

A square pyramid has a base with four sides, which are all triangles. So, it has one triangular base.

A pentagonal pyramid has a base with five sides, forming five triangles. So, it also has one triangular base.

Therefore, among three square pyramids and two pentagonal pyramids, there are a total of 3 + 2 = <<3+2=5>>5 triangular bases.
the answer is zero bc it asked how many truiangular bases
