The formula to calculate the surface area of a box is 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height.
Given:
Length (l) = 7 inches
Width (w) = 3 inches
Height (h) = 5 inches
Plugging these values into the formula:
Surface Area = 2(7)(3) + 2(7)(5) + 2(3)(5)
Surface Area = 42 + 70 + 30
Surface Area = 142 square inches
Therefore, the surface area of the box is 142 square inches.
what is the surface area of the box? 7 in by 3 in by 5 in
