Question

# The traversers are adding a new room to their house. The room will be a cube with a volume of 6589 cubic feet .They are going to put in hardwood floors , which costs Rs 10 per square foot . How much will the hardwood floors cost ?

Hint:

### Find the area of the room in square feets and then calculate the cost

## The correct answer is: 3610 Rs

### Complete step by step solution:

Volume of the cube shaped room = 6589 cubic feet…(i)

Let the side of room = x

We know that the formula for volume of a cube = x^{3}…(ii)

On equating both, we get x^{3} = 6589

Now take cube roots on both the sides, we have

Cost of hardwood floor for 1 square feet = Rs 10

Here we have 19 square feet,

∴ Cost of hardwood floor for 19 square feet = Rs
