The cost of the paint is Rs. 36.50 per kg. If 1 kg of paint covers 16 square feet, how much will it cost to paint outside of a cube having 8 feet each side.
Rs. 850
Rs. 860
Rs. 876
Rs. 886
Explanation:
We will first calculate the Surface area of cube, then we will calculate the quantity of paint required to get answer.
Here we go,
Surface area =6$a^2$=6∗$8^2$=384sq feet
Quantity required =384/16=24kg
Cost of painting =36.50∗24
=Rs.876
