Find the surface area of the prism.

A solid with six rectangular faces that has length 3 inches, width 8 inches, and height 11 inches.

3 in

8 in

11 in

The surface area of the prism is

nothing insquared.

290 in²

Step-by-step explanation:

The surface area of a prism is found using the following formula: SA = 2 (lh+lb+bh). This formula takes the area of each face (6 in total (and adds them together to find a total sum. Substitute l = 3, b = 8 and h = 11 to solve for the surface area.

SA = 2 (lh+lb+bh)

SA = 2 (3*11+3*8+8*11)

SA = 2 (33 + 24 + 88)

SA = 2 (145)

SA = 290
