can anyone help me with math?

Question

the question says to - find the surface area of the right prism and the pic looks like a 3-D triangle with 3 rectangle .....help me plzz

Answer 1

Grab some imaginary play-do, roll it in a ball. Flatten the top and bottom, to make a cylinder.
Get an imaginary cookie cutter, shaped like a triangle, and cut a triangle out of the play-do. throw away the waste, and look at your imaginary cookie.

The top and bottom should be triangles. The SIDES should be rectangles.

Now, the area! Three rectangles, each of an area of (triangle side) x (cookie depth). Add the area of the top triangle, and add it again for the bottom triangle.

Hope that helps....
