ys there are 15

Answer 5

So, they're basically just squares, right? What's the area of 15 of those squares?

45?

Answer 7

You multiplied 15 to 3 :P

the area of one square with a side measuring 3 is what now?

Answer 8

We're still not done. At the base of your solid, there are two edges with 5 square faces, and two edges with 3 square faces, right? That makes 5 + 5 + 3 + 3 = 16.
