Determine the surface area
The figure is made up of two cuboids and the surface area of a cuboid is:

Because the bottom part of the upper piece is not visible, the area is calculated as:

This gives:


For the bottom piece:
We calculate its area as
. However, the area of the invisible part will be subtracted.
So, we have:


The total surface area is:


The length of BC would be 6ft
The multiply choice were worth 4 points.
Gretchen= 18x+19
Ezia= 15x+31
So basically you can enter any number. At first I picked 3 and then I did the math and I got 73 points for Gretchen and 76 points for Ezia.
Then I pick four and then I got 91 points for them both. This is how I got the answer:
18x+19=15x+31
18(4)+19=15(4)+31
72+19=60+31
91=91
