Question

find the surface area of the triangular prism. next, find the area of both triangles. (multiply by 2.) area of 1 triangle: 18 cm² area of both triangles: ? cm² area of the bottom rectangle area of the ba rectang area of the ma

Explanation:

Step1: Identify the operation

We know the area of 1 triangle is \( 18 \, \text{cm}^2 \), and we need to find the area of both triangles by multiplying the area of one triangle by 2.

Step2: Perform the multiplication

The formula to find the area of both triangles is \( \text{Area of both triangles} = 2 \times \text{Area of 1 triangle} \). Substituting the given value, we get \( 2 \times 18 \).
Calculating \( 2 \times 18 = 36 \).

Answer:

\( 36 \)
