Jennifer got a box of chocolates. The box is a right triangular prism shaped box. It is 7 inches long, and the triangular base measures 3in x 4in x 5in. What is the surface area of the box of chocolates?

Answer 1

A 3-4-5 triangle is a right triangle, so its area is 1/2 * 3*4 = 6
The sides are all rectangles of height 7.
So now just add up the areas of the two bases and the three sides.
