Answer:

we need 21 cartons to cover 63 cubic feet

Step-by-step explanation:

To start we have to find the volume of a single cardboard box

3 cartons hold 9 cubic feet of space

b = box

we divide by 3 of both sides and find how much volume a box has

3b = 9

3b/3 = 9/3

1b = 3

Now if it tells us that we have a volume of 63 cubic feet and our boxes cover 3 cuvic feet we have to divide 63 by 3

63 / 3 = 21

we need 21 cartons to cover 63 cubic feet
