Question
What is the volume of the largest sphere that can be
carved out of a wooden cube of sides 21 cm? (Ο Β = 22/7)Solution
Given that sphere is curved out of a wooden cube. Here we can see that the diameter of sphere will be equal to the edge of cube. Diameter = edge of cube 2r = 21 r = 21/2 cm Volume = 4/3 ΓΒ Ο r3 = 4/3 Γ 22/7 Γ 21/2 Γ 21/2 Γ 21/2 = 4850 cm3
