What is the nursing length of a rectangular prism where the height and width are both 9 cm and the surface area is 432 cm with a small two on the top

Answer 1

The formula for the surface area of a rectangular prism is 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height.

Given that the height and width are both 9 cm, and the surface area is 432 cm^2, we have:

2(9)(l) + 2(9)(9) + 2(9)(9) = 432
18l + 162 + 162 = 432
18l + 324 = 432
18l = 108
l = 6

Therefore, the length of the rectangular prism is 6 cm.
