Why are you changing names with each post?
I don't know if you are talking about a right angle prism (with traingular cross section) or a rectangular prism. In either case, add the areas of the sides.
Find the surface area of the right prism. The height is 2.5 cm, the lenght is 8 cm, and the width is 5.3 cm.
This is confusing. I need help.
