Question

What is the surface area of the right rectangular prism?

Answer 1

252 in²

Explanation:

You have to calculate the area of each surface and sum all they after:

Top area: 6 × 12 = 72 in

Front area: 3 × 12 = 36 in

Side area: 6 × 3 = 18 in

You have 2 rectangles with the same measure of the top, of the side and the front, so multiply each area per 2:

72 × 2 = 144

36 × 2 = 72

18 × 2 = 36

Now you sum all the areas:

144 + 72 + 36 = 252 in²

Answer 2

Hello! answer:

Explanation:

6 × 12 = 72

6 × 12 = 72

3 × 12 = 36

3 × 12 = 36

3 × 6 = 18

3 × 6 = 18

72 + 72 + 36 + 36 + 18 + 18 = 252 therefore the surface area would be 252 hope that helps!
