What is the surface area of the right rectangular prism, in
square centimeters?

Answer 1

582 cm²

Explanation:

The main vertical rectangle in the middle is 13 cm wide. Its length is

10 cm + 7 cm + 10 cm + 7 cm = 34 cm

Then each of the two rectangles on the sides is 10 cm by 7 cm.

area = 13 cm × 34 cm + 2 × 10 cm × 7 cm

area = 582 cm²
