Question
The volume of a solid cube is 1728 m3. If
whole cube is to be painted at a rate of Rs. 6.5 per m2, then what will be the cost of painting the cube?Solution
Let the edge length of the cube = ‘a’ metres Then, volume of the cube = a3 = 1728 So, a = 1728(1/3) = 12 So, total surface area of the cube = 6a2 = 6 × 122 = 864 m2 So, cost of painting the cube = 864 × 6.5 = Rs. 5616
