Can someone find the surface area for me?

9514 1404 393

  876 square inches

Step-by-step explanation:

The total surface area is the sum of the areas of the two triangular bases, and the lateral area--the sum of the areas of the three rectangular faces.

Total triangle area:

  2(1/2)(bh) = bh = (26 in)(6 in) = 156 in²

Rectangular face area is the product of the length of the prism (12 in) and the perimeter of the base:

  (12 in)(26 in + 24 in +  10 in) = (12 in)(60 in) = 720 in²

Total area is then ...

  base area + lateral area = 156 in² +720 in² = 876 in²

Comment on the question

The geometry shown is impossible. The base width must be about 31.24 inches for the other dimensions to be accurate.
