Answer:
77cm²
Step-by-step explanation:
Okay, so first you have to find the area of all the shapes that make up the net, I'm going to start with the triangle:
So the height is 2 and the base is 5, so we plug this into our equation to get:
2 x 5 ÷ 2 = 5
There's 2 triangles so:
5 x 2 = 10
Then we start on the rectangles, we're going left to right:
6 x 3 = 18
5 x 5 = 25
4 x 6 = 24
Then we add that all up:
10 + 18 + 25 + 24 = 77
So the net of the triangular prism is 77cm²
hope this helps:)
