the base of a right triangular prism has a width of 8 inches and a height of 6 inches. the length of the third side of the triangle is 10 inches and the length of the prism is 12 inches. What is the surface area of this prism?

  • geometry - ,

    I see a surface area of the prism to be made up of 2 triangles and 3 rectangles
    Hypotenuse of triangle is 10 (double the 3,4,5 triangle, it was actually given even though it could have been found)
    So area = 2(1/2)(6)(8) + 10(6) + 10(8) + 10(10) = 288 inches^2
