If a box has a surface area of 150 square inches and its height is 5 inches, what are the possible dimensions of the base?

• Dimensions must be equal, l = w = 10 inches

• Possible dimensions of the base (l, w) can be found by solving the equation lw + 5l + 5w = 75 for positive values of l and w.

• The height must be included in the base area calculation

• The base dimensions cannot exceed 30 inches each
