Question

Find the surface area of the prism. (5m, 4m, 3m) (Numbers listed from top of prism to bottom)

Answer 1

You have to find the surface are for each face of the prism. The dimensions for each face would be:
1: 5m, 4m
2: 4m,3m
3: 3m, 5m

Each face is repeated on the prism so you can multiply the answer at the end to figure out the answer for all 6 sides.

The equation would be:
SA=[(5*4)+(4*3)+(3*5)]2

The answer would be 94m squared.

Answer 2

your answer should be 12
