ABC Elementary wants to purchase new computers for their school. They are curious

Question

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

To find the surface area of the laptop, we need to find the area of each side and then add them together.

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

Surface Area = 2lw + 2lh + 2wh

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

Substitute the values into the formula:

Surface Area = 2(13)(7.5) + 2(13)(7.5) + 2(7.5)(7.5)
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.
