When Antonio opens and lays a cereal box out flat, he sees that the top and the bottom of the box each measure 2 inches by 7 inches, the sides of the box each measure 2 inches by 12 inches, and the front and back of the box each measure 7 inches by 12 inches. What is the surface area of Antonio's cereal box
Answered by Reiny
The result of laying out a box like that is called a net.
you will see 3 pairs of sides,
2 of a 2 by 7
2 of a 2 by 12
2 of a 7 by 12
find the area of each, and add them up
let me know what you got, and I will check your answer
Answered by henry2,
As = (2*7)*2 + (2*12)*2 + (7*12)*2 = ----sq. in.
