Answer: $68,590
The volume of the cube-shaped room is given as 6859 cubic feet, and the cost of hardwood floors is $10 per cubic foot. To find the total cost of the hardwood floors, you can simply multiply the volume of the room by the cost per cubic foot:
Cost of hardwood floors = Volume of room × Cost per cubic foot
Cost of hardwood floors = 6859 cubic feet × $10/cubic foot
Cost of hardwood floors = $68,590
So, the hardwood floors will cost $68,590
