The net of a triangular prism is shown below. What is the surface area of the prism? A. 128 cm^2 B. 152 cm^2 C. 176 cm^2 D. 304 cm^2

B. 152 cm²

Step-by-step explanation:

To find the surface area using a net, do this:

Take apart the figure. We see that there are three rectangles and two triangles. Find the area of each () and then add the values together:

The first rectangle on the left is the same as the one on the right.

Two measures are 40 cm².

The middle rectangle is:

48 cm²

The formula for the area of a triangle is :

The area of the two triangles is 12 cm².

Now add the values:

The area of the figure is 152 cm².
