Question

What is the surface area of the triangular prism?

Answer 1

Answer: 216

Step-by-step explanation:

216 cm2

SA = bh + (s1 + s2 + s3)H

SA = 6(4) + (6 + 5 + 5)12

SA = 24 + (16)(12)

SA = 24 + 192

SA = 216 cm2

Answer 2

Hi there!

To find the surface area, we need to find the area of all of the faces. The triangle face = 4 x 6, and the rectangular faces = 2(5 x 12) + 1(6 x 12). All we are doing is simply finding the area of each face and adding it together. The area of the triangles = 24, and the area of the rectangles = 192. Then, add the two values to get 216cm^2.

Hope this helps!! :)
