Question

Graphene, which is used in the manufacture of integrated circuits, is so thin that a sheet weighing one ounce of cover up to 7 football fields. If a football field has an area of approximated 1 1/3 acres, about how many acres could 48 ounces of graphene cover?

Answer 1

48 ounces of graphene covers 448 acres.

Explanation:

One ounce of graphene cover football fields = 7

Area of 1 football field =
`1 (1)/(3) = (4)/(3) acres`

Area of 7 football fields =
`(4)/(3) * 7 = (28)/(3) acres`

So, 1 ounce of graphene cover acres of field =
`(28)/(3)`

48 ounces of graphene cover acres of field =
`(28)/(3) * 48 = 448 acres`

Hence 48 ounces of graphene covers 448 acres.
