The Bells are adding a new room to their house. The room will be a cube with a volume of 4,913 cubic feet. They are going to install hardwood floors, and the contractor charges $5 per square foot. How much will the hardwood floors cost?

Answer :

Answer:

$1445

Step-by-step explanation:

The side length of the room is the cube root of the volume of the cube:

s = ∛4913 = 17 . . . . feet

The area of the floor is the square of this side length:

A = (17 ft)² = 289 ft²

The cost of the floor is $5 for each square foot:

cost = ($5/ft²)(289 ft²) = $1445

The hardwood floor will cost $1445.
