7.2 Surface Area and Volume of Prisms

Below is a net for a right rectangular prism. What is the surface area?

First, you need to find the area of each base. B=1/2 (4)(24)=96 Then, find the perimeter of each base. P=12+24+20=56 So, the lateral face is... [L=hp] L=40(56)=2,240 Lastly, plug in the numbers to your surface area formula. [S=L+2b] S=2,240+2(96) or S=2,240+192=2,432

answer: 2,432 as it's surface area. =]
