ABC Elementary wants to purchase new computers for their school. They are curious how the new laptops compare to their current ones in terms of space as their enrollment numbers are increasing and space is not. What would the surface area be if the length is 13 inches, the width is 7.5 inches, and the height is 7.5 inches? The triangle’s hypotenuse is 10.61 inches. (Remember the hypotenuse is the longest side of the triangle.) Round your answer to the nearest hundredth if necessary.(1 point)

Answer 1

The surface area of the laptop can be calculated using the formula for finding the surface area of a rectangular prism: 2lw + 2lh + 2wh

Given:
Length (l) = 13 inches
Width (w) = 7.5 inches
Height (h) = 7.5 inches

Surface area = 2(13)(7.5) + 2(13)(7.5) + 2(7.5)(7.5)
Surface area = 2(97.5) + 2(97.5) + 2(56.25)
Surface area = 195 + 195 + 112.5
Surface area = 502.5 square inches

Therefore, the surface area of the laptop would be 502.5 square inches.
