Acandy bar box is in the shape of a triangular prism. the volume of the box is 2,400 cubic centimeters.
part a: what is the height of the box? show your work.
part b: what is the approximate amount of cardboard used to make the sides of the candy box? explain how you got your answer.

A: height = 30 cm. Work: Read the previous

sentence, where it says the length (= height)

of the box is 30 cm.

B: To make the box, we need 2 triangular ends,

and 3 rectangular sides. Side the volume = 3240

and the height = 30, the area of each base (end) = 108.

The sides have areas of 30 x 42 = 720, and 30 x 15 = 450,

and there are 2 of those. So total area = 108 + 108 + 720 + 900 = 1836 cm^2
