To calculate the surface area of the box, you need to find the area of each of the six faces (top, bottom, front, back, left side, right side) and then add them together.
The formula to find the surface area of a rectangular box (or rectangular prism) is:
Surface Area = 2lw + 2lh + 2wh
Given the dimensions:
Length (l) = 9 cm
Width (w) = 5 cm
Height (h) = 8 cm
Plugging these values into the formula:
Surface Area = 2(9)(5) + 2(9)(8) + 2(5)(8)
Surface Area = 90 + 144 + 80
Surface Area = 314 square cm
Therefore, the surface area of the box is 314 square cm.
what is the surface area of the box? 5 cm by 9 cm by 8 cm
