Answer 4

what is the formula?

rectangular prism formula= 2*b+p*h

Answer 6

Find the area of the triangle and multiply it by 2. Then find the perimeter of the triangle and multiply it by 10

Answer 7

area of the base......

Answer 8

so multiply 10*8= 80 then multiply it by 2

Answer 9

No, we're using the triangle as the base since it's much easier.

160

Answer 11

Chiko, you're doing it the hard way you know.

Answer 12

im just doing it by the way they taught me...

Answer 13

Well there's an easier way. Don't use the rectangle as the base. Use the triangle as the base. So \[(\triangle area*2)+(\triangle perimeter * 10)\] Find the triangle area and perimeter then plug it in for the answer.

Answer 14

CONFUSED IM ABOUT TO DIE!

Answer 15

so take the p and multiply it by 3 and and then add what you got to 160
