2. What is missing length of rectangular prism if height and width are both 8 inches. And surface area is 256 in^2
To find the missing length of the rectangular prism, we first need to calculate the surface area of the rectangular prism using the formula:
Surface Area = 2lw + 2lh + 2wh
Given that the height and width are both 8 inches and the total surface area is 256 in^2:
256 = 2(8)(l) + 2(8)(8) + 2(8)(8)
256 = 16l + 128 + 128
256 = 16l + 256
16l = 256 - 256
16l = 0
l = 0
Since the length is 0, the assumption might have been incorrect. Please double-check the measurements provided.
