To calculate the surface area is basicall calculating area all that is neccessary is for you too look where the values line up find the area's and add them I will help you get in to the right direction though I will Identify for you what you need to multiply You should be becoming familar with how to do this.

Right triangle \(5 * 12 = area\)

Right triangle \(5 * 12 = area\)

Rectangle that slants along the hypnotuse \(13 * 15 = area\)

Rectangle under the prism \(12 * 15 = area\)

Rectangle in the back of the prism \(5 * 15 = area\)

All you have to do is add products of these problems and tell me what you get.....

For the second part I will give you a hint: Look at the hyptoptuse on the right triangles how long is the rectangle on there???

Ha 9 just relized the triangles are supposed to be times once and then divided by 1/2 is that what I am supposed to do??
