Question
How many triangular bases are there among 3 square pyramids and 2 pentagonal pyramids that Jayla sees on her trip to Egypt?(1 point)

Answer 1

that is not it

Answer 2

To find the total number of triangular bases among the pyramids Jayla sees, let's analyze both types of pyramids:

- A square pyramid has 1 square base and 4 triangular faces (sides).
- A pentagonal pyramid has 1 pentagonal base and 5 triangular faces (sides).

Now, let’s calculate the number of triangular bases:

1. For 3 square pyramids:
- Each has 4 triangular sides, so \(3 \times 4 = 12\) triangular sides.

2. For 2 pentagonal pyramids:
- Each has 5 triangular sides, so \(2 \times 5 = 10\) triangular sides.

Now, add them together to find the total number of triangular bases:
\[
12 \text{ (from square pyramids)} + 10 \text{ (from pentagonal pyramids)} = 22 \text{ triangular sides.}
\]

Thus, the total number of triangular bases is **22**.

Answer 3

I apologize for the confusion. Let's clarify the question.

The question asks for the number of triangular **bases** (not triangular faces) among Jayla's pyramids.

- **Square pyramids** have **1 square base** each and no triangular bases.
- **Pentagonal pyramids** have **1 pentagonal base** each and no triangular bases.

Now, let’s revise:

- **3 square pyramids:** Each has **0 triangular bases**.
- **2 pentagonal pyramids:** Each has **0 triangular bases**.

Therefore, the total number of triangular bases among all the pyramids is:

\[
0 \text{ (from square pyramids)} + 0 \text{ (from pentagonal pyramids)} = 0
\]

So, the answer is **0 triangular bases**. Thank you for your patience!
