what's the question?
Find the surface area of the prism. A. 24 m2 B. 54 m2 C. 94 m2 D. 104 m2
the prism is the link
you need to find the area of all the parts of the prism. Can you do that for me?
ok, the base is 3x4=12
right, and that is the same as the top. So what are the sides?
5 m so 5+5+5+5=20
12+12+20=42
the front and back sides are both 15 because 3x5=15. the top and bottom sides are both 12 because 3x4=12. and the side sides are both 20 because 4x5=20. Now you just need to add them all together twice, because there are two of the same sides. \[12+12+15+15+20+20=?\] can you do that for me?
sorry i have to get off
that's fine. But all you need to do to finish that question is add all those numbers correctly.
