Zoe’s living room rug is 3 feet wide and 7 feet long. She will cover the rug with 6-inch square cardboard pieces for a painting project. How many cardboard pieces will Zoe need?

Answer format: Zoe will need ____ pieces of cardboard.

Answer 1

Zoe will need 504 pieces of cardboard.

Explanation:

Length of room = 7 feet =
`7*12=84` inches

Width of room =3 feet =
`3*12=36` inches

Area of room in square inches

⇒ Length in inches
`*` width in inches

⇒
`84* 36`

⇒
`3024` square inches

Area of each cardboard piece used to cover the rug =6 square inches

So, number of cardboard pieces Joe will need to cover the rug would be

⇒
`(Area\ of\ room\ rug)/(Area\ of\ each\ cardboard\ piece)`

⇒
`(3024)/(6)`

⇒
`504`

So, Zoe will need 504 pieces of cardboard.
