Question
Find the surface area of the smallest cube that can
perfectly fit a sphere of volume 12348Ï€ cm3 inside it. ÂSolution
Let the radius of the sphere be 'R' cm. 12348π = (4/3) x π x R3 Or, 9261 = R3 So, R = 21 So, length of edge of the cube = 21 x 2 = 42 cm Required area = 6 x 422 = 10584 cm2
