The length of the side of a cube is 4.2 cm. What is the volume of the largest sphere that can be taken out of the cube?
Answer & explanation
Correct answer: option 3
We know that,
Volume of a sphere = \(\frac{4}{3}\)πr3
The length of the side of a cube = 4.2 cm.
Diameter = 4.2 cm
Radius = 2.1 cm3
Now, the volume of the sphere = \(\frac{4}{3}\) × \(\frac{22}{7}\) × (2.1)3 = 38.80 cm3
