Can some one me and quick! only answer if you know and explain how you got it!
a candy bar box is in the shape of a triangular prism. the volume of the box is 2,400 cubic centimeters. a triangular prism is shown with base of triangle labeled 16 cm, sides of triangles labeled 17 cm, and length of the box equal to 20 cm.
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.

Notice the first picture here
to get the height of the box, or triangular prism,
you need to find the "altitude" of the triangle,
and for that, you can simply use the pythagorean theorem,
notice, as 17 is the slanted or hypotenuse side,
and 8 is the base, or half 16

now, how much cardboard? meaning, how much is the
surface are of that triangular prism
notice the 2nd picture here

the prism is really just 3 rectangles and 2 triangles,
stacked up at each other at the edges, so
split them up, find their independent areas,
recall area of a triange = 1/2 b*h
and them SUM them up

and that's the surface area of that triangular prism,
and thus the box, and that's how much cardboard
was used
