Question

A shipping carton for a poster has the shape of a triangular prism. the triangular end of the carton has a base that is 5 inches long and a height of 4 inches. the carton is 25 inches long from front to back. what is the volume of the carton?

Answer 1

The volume of any prism is \[V=A_b \times H\] in this case our base is a triangle so to find the area of the base we need to: \[A=\frac{b \times h}{2}\] then we can solve for the volume by substituting in known values.

Answer 2

Lol I still don't understand a little -_-

Answer 3

so is it like 5x4/2?

Answer 4

Yes, that will get you the area of the base \[A=\frac{5 \times 4}{2}\] which is the first step.

Answer 5

That equals 10

Answer 6

Yes it does.

Answer 7

so what do I do with the 25? multiply it?

Answer 8

The formula for volume is \[V=base \times height\] You just found the base and they give you the height. You can get the volume by plugging in the numbers you know.

Answer 9

Wow thanks I understand now!

Answer 10

No problem.
