Use the net to determine the total surface area. The net of a prism with width 10 inches, length 5 inches, and height 7 inches is laid flat. 330 in2 270 in2 310 in2 350 in2

We are asked to solve for the surface area of the described figure in the problem. We can conclude that the given figure is a rectangular prism since it was being mentioned in the problem that the height is laid flat. Therefore, the formula for the surface area is SA = PH + 2B where "P" stands for the perimeter of the rectangle and "B" stands for the area of the rectangle while "H" is for the height.

Solving for P, we have it:

P = width + length + width + length

P = 10 + 5 + 10 + 5

P = 30 inches

Solving for B, we have it:

B = length * width

B = 10 * 5

B = 50 inches squared

Solving for the surface area, we have it:

SA = PH + 2B

SA = 30*7 + (2*50)

SA = 310 inches squared

The answer is 310 in2.
