Answer: 952 ft squared

Step-by-step explanation:

Surface area, is just the area of all the faces added together.

So, the sides we need to find are measuring:

Triangle side: 10 x 8

Triangle Face; 10 x 8

Square Face: 10 x 10

Square Face: 10 x 10

Rectangular Face: 14 x 10

Rectangular Face: 14 x 10

Bottom Rectangular face: 14 x 10

Side of the Triangular prism: 9 x 14

Side of the Triangular prism: 9 x 14

Because the triangle face has two of them, we only have to do one as opposed to dividing the same face twice.

So, we have a side of 80.

From here, it is just multiplication.

80 + 100 + 100 + 140 + 140 + 140 + 126 + 126 = 952 ft
