What is the surface area of this design?
A.76in2
B.280in2
C.360in2
D.392in2

There are 8 faces on the figure.

There are two of the same sides so we can multiply that by 2. That side equals 76 in. 76 x 2 = 152.

Then, there is another side that equals 4 x 4 which is 24.

Another side equals 4 x 6 which is 24.

Another one equals 6 x 6 which is 36.

Another side equals 6 x 6 which also equals 36.

Another side equals 10 x 6 which is 60.

The last side is 10 x 6 which equals 60.

Which should add up to 392 in.
