Question
Find the surface area of the smallest cube that can
perfectly fit a sphere of volume 47916Ï€ cm3 inside it. ÂSolution
Let the radius of the sphere be 'R' cm. 47916π = (4/3) x π x R3 Or, 35937 = R3 So, R = 33 So, length of edge of the cube = 33 x 2 = 66 cm Required area = 6 x 662 = 26136 cm2
