The cost of painting the whole surface area of a cube at the rate of is 10 paise per cm2Rs. 264.60. Then, the volume of the cube is

Let the side of cube be ‘a’

Hence total surface area of cube = 6a2


Cost of painting the cube = 6a2 × 10


264.6 = 60 a2


a2 =


a2 = 4.41


a = 2.1


Hence,


Volume of the cube= a3


= (2.1)3


= 9.261 cm3


Hence, option B is correct
