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]
