Question

A rectangular prism and its dimensions are shown in the diagram.

base are 7.5 and 5 and height is 6.5


Which measurement is the closest to the total surface area of this prism in square inches?

Answer 1

Answer: The total surface area of a rectangular prism can be found using the formula:

SA = 2lw + 2lh + 2wh

where l, w, and h are the length, width, and height of the rectangular prism, respectively.

Substituting the given values, we get:

SA = 2(7.5)(5) + 2(7.5)(6.5) + 2(5)(6.5)

SA = 75 + 97.5 + 65

SA = 237.5

Therefore, the closest measurement to the total surface area of the prism is 237.5 square inches.
