Q:
# WILL GIVE THE BRAINLEST Find the surface area of the solid figure

Accepted Solution

A:

Answer:3,380 ft²Step-by-step explanation:We will look at this as the rectangular prism, and the triangular prismThe surface of the rectangular prism...The front and back are rectangles with dimensions of 20x36, there are 2 rectangles, so the area is...2(20x36) = 2(720) = 1.440The top and bottom of the are rectangles with dimensions of 10x36, there are 2 rectangles, so the area is...2(10x36) = 2(360) = 720The left side is a rectangle with dimension of 10x20, so the area is 10(20) = 200The triangular prism...the front and back are triangles with a height of 20 and a base of 24, there are 2 triangles, so the area is...2[(1/2)(20x24)] = 2[(1/2)(480)] = 480The bottom is a rectangle with dimensions of 24x10, the area is 240The top of the triangle is a rectangle with dimensions of 10x30, the are is 300Putting them all together gives us..1,440 + 720 + 200 + 480 + 240 + 300 = 3,380 ft²
