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

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
