!pls help!<br> Use a net to find the surface area
Maurinko [17]

Answer:

336 square inches

Step-by-step explanation:

Nets are the spreaded out version/outline of 3d figures. It shows the faces of the figure. The figure in this case is actually a triangular prism.

find the area of each shape in the net:

Triangle A (1/2 x base x height)

1/2 • 8 x 6 = 24 square inches

Rectangle B (length x width):

6 x 12 = 72 square inches

Rectangle C:

8 x 12 = 96 square inches

Rectangle D:

10 x 12 = 120 square inches

Triangle E:

1/2 x 6 x 8 = 24 square inches

Add up all the areas of all shapes:

24 + 24 + 120 + 72 + 96 = 336

Surface area is measured in square inches

(Inches in this case)

Hope this helps

valkas [14]

Answer:

88 degrees

Step-by-step explanation:

First add up all of your degrees

85+ 87+ 83+ 88+ 91+ 87+ 95= 616

Then divide that amount by the amount of different degrees you had in the question. You have 7 different degrees, so you will divide by 7.

616/7= 88

And boom you have your answer
