(05.06)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 8 feet. the first and second rectangles length are unknown, and the last is 13 feet long. there are two right triangles above and below the last rectangle. one is labeled with a base of 5 feet and a height of 12 feet.

1. 88 square feet
2. 232 square feet
3. 283 square feet
4. 300 square feet

The answer is 300

Step-by-step explanation:

The triangle formula = ( B · H) ÷ 2

B = 5     H = 12     5 · 12 = 60 ÷ 2 = 30

Since there is two triangles you will have two 30's.

The rectangle farthest to the right = 13 · 8 = 104

If you unfold the triangle it will line up perfectly with the 3 rectangles, so...

The middle rectangle = 5 · 8 = 40

The rectangle farthest to the right = 12×8 = 96

Add them all up

30 + 30 + 104 + 40 + 96 = 300

Hope this helped!

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
