To find the surface area of a box, you need to calculate the area of each individual side and add them together.
The box has 6 sides: a top, a bottom, a front, a back, and two sides.
Top and bottom: 5 in x 8 in = 40 square inches each
Front and back: 5 in x 4 in = 20 square inches each
Sides (2): 8 in x 4 in = 32 square inches each
Total surface area = 2(40) + 2(20) + 2(32) = 80 + 40 + 64 = 184 square inches
So, the surface area of the box is 184 square inches.
what is the surface area of a box that is 5 in by 8 in by 4 in?
