Answer:

The cost will be $3,610

Step-by-step explanation:

Remember that the volume of a cube is

[tex]V=b^{3}[/tex]

where

b is the length side of the cube

we have

[tex]V=6,859\ ft^3[/tex]

substitute in the formula and solve for b

[tex]6,859=b^{3}[/tex]

[tex]b=\sqrt[3]{6,859} =19\ ft[/tex]

The area o the floor will be

[tex]A=b^2[/tex]

substitute

[tex]A=19^2=361\ ft^2[/tex]

Find out the cost of the hardwood​ floors

Multiply by $10 the area of the floor

[tex](10)361=\$3,610[/tex]
