Question

HELP ME PLEASE!!!!!!

Answer 1

The answer is 94 square inches.

First you have to find area of all the sides of the shape.

You so this by multiplying 4*5=20, 3*4=12, and 3*5=15

Then double all the products because there are two of each one of the sides on the shape because it is a rectangular prism.

You get 40, 24, and 30.

Finally add all of those numbers together to get the surface area. 40+24+30=94.

94 is the surface area

Answer 2

94 square inches.

Explanation:

Surface area is the area around a surface. Thus, in order to calculate the surface area of a rectangular prism, we just need to add up the different faces of it.

There are 2 5x4 faces, 2 3x5 faces, and 2 4x3 faces.

Thus, we get 2*20 + 2*15 + 2*12 = 40 + 30 + 24 = 94 square inches.
