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 ?

hintHint:

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 = x3…(ii)
    On equating both, we get x3 = 6589
    Now take cube roots on both the sides, we have x equals cube root of 6589
    not stretchy rightwards double arrow x equals 19 ft
    Cost of hardwood floor for 1 square feet = Rs 10
    Here we have 19 square feet,
    ∴ Cost of hardwood floor for 19 square feet = 19 squared cross times 10 equals 3610 Rs
