A candy bar box is in the shape of a triangular prism. The volume of the box is 3,240 cubic centimeters.
A triangular prism is shown with base of triangle labeled 24 cm, sides of the triangle labeled 15 cm, and length of the box equal to 30 cm.
Part A: What is the height of the box? Show your work. (5 points)
Part B: What is the approximate amount of cardboard used to make this candy box? Explain how you got your answer. (5 points)

Best ResponseYou've already chosen the best response.1the area of the base of your prism, is the area of a triangle whose base and height are 24cm and 15 cm respectively. SO the area of the base of your prism is: A=(24*15)/2=...cm^2

Best ResponseYou've already chosen the best response.1now we can write: volume = base area x height of prism so, we get: \[3240 = 180 \times H\] what is H?

Best ResponseYou've already chosen the best response.1we have two triangles, and the area of each triangle is 180 cm^2, so the base area of your prism is: 180*2=...

Best ResponseYou've already chosen the best response.1using the theorem of Pitagora, we can write: \[\Large AC = \sqrt {C{H^2} + A{H^2}} = \sqrt {{{15}^2} + {{12}^2}} = ...\]
