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

Answer:

Zoe will need 504 pieces of cardboard.

Step-by-step explanation:

Length of room = 7 feet =$7\times12=84$ inches

Width of room =3 feet = $3\times12=36$ inches

Area of room in square inches

⇒ Length in inches $\times$ width in inches

⇒ $84\times 36$

⇒ $3024$ 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

⇒ $\frac{Area\ of\ room\ rug}{Area\ of\ each\ cardboard\ piece}$

⇒ $\frac{3024}{6}$

⇒ $504$

So, Zoe will need 504 pieces of cardboard.
