To find the surface area (SA) of the box of cereal, you need to calculate the areas of all its six faces and then add them together.

The formula for the surface area of a rectangular prism (box) is: SA = 2lw + 2lh + 2wh

Given: Length (l) = 7 inches Width (w) = 2 inches Height (h) = 10 inches

Plug the values into the formula:
SA = 2(7*2) + 2(7*10) + 2(2*10)
= 2(14) + 2(70) + 2(20)
= 28 + 140 + 40
= 208 square inches

So, the surface area of the box of cereal is 208 square inches.
