The travers are adding a new to their house. The room will be a cube with a volume 8,000ft cubed. They are going to put hardwood floors, and the contractor charges 10$ per square foot. How much will the hardwood floor cost?

The answer to your question is: cost = $4000

Step-by-step explanation:

Data

Volume = 8000 ft³

cost = $10 / square foot

Process

It's a cube then we find the length of one side

Volume = l³ = 8000

l = ∛8000

I = 20 ft

Now, calculate the area of the floor,

Area = l x l

= 20 x 20

= 400

Finally, find the cost of the floor

cost = area x price

cost = 400 x 10

= $4000
