Answer:
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.
