The factory is building cardboard cereal boxes. Each box is 10 inches long, 3 inches wide, and 12 inches tall. How many square inches of cardboard will the factory need to build 50 boxes?

18600 square inches

Step-by-step explanation:

To find the number of square inches of cardboard will the factory need to build 50 boxes, we find the total surface area of the cereal box which is A = 2(lw + lh + hw) where l = length of box = 10 inches, w = width of box = 3 inches and h = height of box = 12 inches.

Substituting the values of the dimensions into A, we have

A = 2(lw + lh + hw)

= 2(10 × 3 + 10 × 12 + 12 × 3) in²

= 2(30 + 120 + 36) in²

= 2(186) in²

= 372 in²

So, the area of one box is 372 in². The area of 50 boxes is thus, area of one box × 50 = 372 in² × 50 = 18600 in²

So we require 18600 square inches of cardboard to build 50 boxes.

the correct answer is x/3+10≥32

hope this !
