Question

Use a net to find the surface area of the right triangular prism shown below:

Three rectangles next to each other with a width of 7 feet. The first and second rectangles length are unknown, and the last is 10 feet long. There are two right triangles above and below the last rectangle. One is labeled with a base of 6 feet and a height of 8 feet.

198 square feet
216 square feet
270 square feet
280 square feet

Answer 1

Haha, is there a picture that you can upload?

Answer 2

there you go

Answer 3

Hello?

Answer 4

Looking at it

Answer 5

Length of the middle one is 6

Answer 6

Length of the first one is 8

Answer 7

Length of the last one is 10 of course

Answer 8

First Rectangle: l times w = 8 times 7
Second Rectangle: l times w = 6 times 7
Third Rectangle: l times w = 10 times 7
Both Triangles: base times height 6 times 8

Formula for the area of a triangle is base times height divided by 2, but since we have two identical triangles there is no need to divide.

Do all the calculations and you should have your answer :)
