Probably you just need to work out how many curved surfaces for the cylinder you can cut from the strip.
Basically, you must convert yards to inches.
As 1 yard = 3 feet
3 feet = 12 inches,
there are 36 inches in a yard.
The strip is 36 by 72 inches in area.
You must find the surface area of a 1000 cubic inch volume cylinder.
If you allow the height of the cylinders to be 1 yard = 36 inches,
then you can work out the cylinder radius from the volume formula.
Then you can use the surface area formula to discover the curved surface area of the "1000 cubic inch"-volume cylinder.
As you are not given height or radius of the cylinder,
it's convenient to choose the height to equal one side of the strip.
