Question

A rectangular prism and its dimensions are shown in the diagram.

What is the total surface area of this rectangular prism in square inches?​

Answer 1

SA=78.5

Explanation:

Find the area to all visible sides. 4*2.5=10, 10*2 (because there is two of these shapes) is 20. 4.5*4=18, 18*2=36. Finally, 4.5*2.5=11.25, 11.25*2=22.5.

20+36+22.5=78.5
