how many triangular bases are there among 3 square pyramids and 2 pentagonal pyramids that Jayla sees on her trip to Egypt
wouldnt.. there be 0? if it's 3 square pyramids, and 2 pentagonal pyramids.. there wouldn't be ANY triangular bases..
its say its wrong
The base of a pentagonal pyramid has 5 edges.
there is a row of two triangular pyramids and one pentagonal pyramid in a display at a museum how many lateral faces are there together
how many edges does the base of a pentagonal pyramid have
A triangular pyramid has 3 lateral faces, and a pentagonal pyramid has 5 lateral faces. In the given display, there are 2 triangular pyramids and 1 pentagonal pyramid.
Total lateral faces = (number of triangular pyramids x number of lateral faces in a triangular pyramid) + (number of pentagonal pyramids x number of lateral faces in a pentagonal pyramid)
= (2 x 3) + (1 x 5)
= 6 + 5
= 11
Therefore, together, there are 11 lateral faces in the display.
Among the 3 square pyramids and 2 pentagonal pyramids that Jayla sees on her trip to Egypt, there are a total of 5 triangular bases.
Each square pyramid has 1 triangular base, so 3 square pyramids will have 3 triangular bases.
Each pentagonal pyramid also has 1 triangular base, so 2 pentagonal pyramids will have 2 triangular bases.
Therefore, the total number of triangular bases is 3 + 2 = 5.
Apologies for the incorrect response. Let's reevaluate the question.
A square pyramid has 1 triangular base, and a pentagonal pyramid has 1 triangular base as well. Given that Jayla sees 3 square pyramids and 2 pentagonal pyramids, the number of triangular bases among them will be 3 (from the square pyramids) + 2 (from the pentagonal pyramids) = 5.
Hence, there are a total of 5 triangular bases among the 3 square pyramids and 2 pentagonal pyramids that Jayla sees on her trip to Egypt.
