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.0That is the height of the triangle, not the height of the triangular prism. The height of the triangular prism is 30 I don't get it. Let's get help @ganeshie8

Best ResponseYou've already chosen the best response.0@ganeshie8 What is wrong with this? the height of the prism =30, the triangle base has the height (h_1)= 9 Volume of the prism is \(V= \dfrac{1}{2} Area_{base}*h= \dfrac{1}{2}*{\dfrac{1}{2}*24*9}*30= 1620\) But the given information gives us Volume of the prism is 3240 which is double with what I have. What is wrong with my calculation???

Best ResponseYou've already chosen the best response.0well do you think you could help with this one then? An image of a prism is shown below: A square prism is shown. Part A: A cross section of the prism is cut with a plane parallel to the base. What is the name of the shape created by the crosssection? (5 points) Part B: If a cross section of the prism is cut diagonal to the base, what would be the shape of the resulting cross section? (5 points)

Best ResponseYou've already chosen the best response.0If I go another way, I got right answer with taking the base is the rectangular Hence the Area of the rectangular is 24*30 = 720 \(V = (1/2) *720 *h= 3240\) hence h = 9.

Best ResponseYou've already chosen the best response.0But ,they MUST be the same while the measure of the sides are the same, right? What is wrong with the first logic???

Best ResponseYou've already chosen the best response.0for the main question, 30 is indeed the height of triangular prism as it is the distance between bases; the teacher who cooked up this problem seems to be careless, not honoring the usual terminology. he is wrongly using "height of prism" to refer to "height of base triangle"

Best ResponseYou've already chosen the best response.0\[\large h^2+12^2 = 15^2 \implies h = 9 \] dw:1437540265309:dw
