Answer 1

Surface area means all of the outside areas, kind of like when you wrap a present.

Explanation:

1st draw the box and find the area of the top and the bottom of the figure

10 x 3 = 30 for the top and 30 for the bottom, so 60 for both.

2nd find the area of two opposite sides:

10x 4.5 = 45 for one side and 45 for the other side, which is 90 for both

3rd find the area of the last two opposite sides:

3 x 4.5 = 13.5 for one side and 13.5 for the other side, so 27 for both.

4th: now add all those sides 60 + 90 + 27 = 177 inches squared.
