Final answer:
To find the total surface area of a rectangular prism, use the formula Surface Area = 2lw + 2lh + 2wh and substitute the given dimensions. The total surface area of the prism is 260 square inches. Therefore, the correct answer is C) 260.
Step-by-step explanation:
To find the total surface area of a rectangular prism, we need to calculate the area of each of its six faces and add them together. The formula for the surface area of a rectangular prism is:
Surface Area = 2lw + 2lh + 2wh
Substituting the given dimensions, we get:
Surface Area = 2(6.5in)(5in) + 2(6.5in)(7.5in) + 2(5in)(7.5in)
Calculating this expression, we find the total surface area of the prism to be 260 square inches. Therefore, the correct answer is C) 260.
