Answer:
171 m
Explanation:
Okay, so we have to find the area of all the shapes that make up the prism:
I'm going to start with the side rectangles:
5 x 7 = 35
There's 2 of them so:
35 x 2 = 70
Now let's go onto the side triangles:
4 x 6 = 24 (normally it would then be ÷ 2, but because there's 2 triangles, you don't have to do that)
Then we do the bottom rectangle:
6 x 7 = 42
So, adding them all together:
35 + 70 + 24 + 42 = 171
So the surface area of the prism is 171 m
hope this is right:)
