Answer:
768 Square Feet
Explanation:
The formula for the surface area of a rectangular prism is:
SA = 2lw + 2lh + 2wh
where l, w, and h are the length, width, and height of the rectangular prism.
Substituting the given values, we have:
SA = 2(10 x 12) + 2(10 x 12) + 2(12 x 12)
SA = 240 + 240 + 288
SA = 768 ft^2
Therefore, the surface area of the rectangular prism is 768 square feet.
