Answer:
$3610.
Step-by-step explanation:
We have been given that the traverses are adding a new room to their house. The room will be a cube with a volume of 6,859 cubic feet. We are supposed to find the hardwood floor's cost.
First of all, we will find side length of cube taking cube root of 6,869.
[tex]\text{Side length of cube}=\sqrt[3]{6,859\text{ ft}^3}[/tex]
[tex]\text{Side length of cube}=19\text{ ft}[/tex]
Now, we will find area of hardwood floor by taking square of 19 ft.
[tex]\text{Area of hardwood floor}=(19\text{ ft})^2[/tex]
[tex]\text{Area of hardwood floor}=361\text{ ft}^2[/tex]
Since hardwood floors costs $10 per square foot, so cost of square foot would be 10 times .
[tex]\text{Total cost of hardwood floor}= \frac{\$10}{\text{ft}^2}\times 361\text{ ft}^2[/tex]
[tex]\text{Total cost of hardwood floor}=\$10\times361[/tex]
[tex]\text{Total cost of hardwood floor}=\$3610[/tex]
Therefore, the cost of hardwood floor would be $3610.
