Question

Pleaseeeee Help!

Use the figure below:

Assume that the 3 x 5.5 m rectangles on the right and left are the bases.

1. What is the surface area of the prism?
2. What is the lateral surface area of the prism?

Answer 1

well, you have 2 endpoints, one of the left and one on the right, they're both 2 rectangles, 3x5.5 each, so you add those

then you have 4 longer faces, the lateral ones, 2 of them are 17.2x3 [horizontal ones]
the other 2 [vertical ones] are 17.2x5.5

so you add those too, and you get the SURFACE area :)

Answer 2

now, the "lateral" surface, well, that's just the value of adding the longer sides, the ones facing horizontally and the other 2 facing vertically :)

Answer 3

Thank you!
