Answer:

290 in^2

Step-by-step explanation:

So what you do is you use the formula of the surface area of a rectangle which is SA=2lw+2lh+2hw.

The length=5. The width=5. The height=12.

You put those numbers into the formula.

2(5)(5)+2(5)(12)+2(12)(5)=290 in^2.

The answer is 290 inches squared.
The surface area is = the sum of all sides. There are 4 sides that equal 60 (60 x 4 = 240), and 2 sides that equal 25 (25 x 2 = 50), the surface area is equal to 240 + 50 which equals 290.
