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 total surface area of the prism.

The surface area formula for a rectangular prism is:
Surface Area = 2lw + 2lh + 2wh

Given:
Height (h) = 8 inches
Width (w) = 8 inches
Surface Area = 256 in^2

Plugging in the given values, we get:
256 = 2(8)(8) + 2(8)(8) + 2(8)(w)
256 = 128 + 128 + 16w
256 = 256 + 16w
0 = 16w
w = 0

Since the width of the prism cannot be 0, there is likely a mistake in the calculations or information given. Please double-check the values provided or provide more information for an accurate calculation.
