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

Answer:

48 ounces of graphene covers 448 acres.

Step-by-step explanation:

One ounce of graphene cover football fields = 7

Area of 1 football field =$1 \frac{1}{3} = \frac{4}{3} acres$

Area of 7 football fields = $\frac{4}{3} \times 7 = \frac{28}{3} acres$

So, 1 ounce of graphene cover acres of field = $\frac{28}{3}$

48 ounces of graphene cover acres of field = $\frac{28}{3} \times 48 = 448 acres$

Hence 48 ounces of graphene covers 448 acres.
