How many triangular bases are there among three square pyramids into pentagonal pyramids
To figure out the number of triangular bases among three square pyramids that form pentagonal pyramids, we need to look at the structures of these pyramids.
A square pyramid has a square base and four triangular faces. However, when three square pyramids come together to form a pentagonal pyramid, only one of the triangular faces from each square pyramid will be a part of the final structure. The other three triangular faces from each square pyramid will be hidden inside the pentagonal pyramid.
Since there are three square pyramids forming the pentagonal pyramid, there will be a total of 3 triangular bases.
Therefore, there are three triangular bases among three square pyramids that form pentagonal pyramids.
