The length of the side of a cube is 2.8 cm. What is the volume of the largest sphere that can be taken out of the cube?
Answer & explanation
Correct answer: option 1
Length of the side of the square = 2.8 cm
Length of cube = Diameter of sphere
The volume of sphere = \(\frac{4}{3}\)πr3
Diameter of sphere = 2.8 cm
Radius of sphere = 1.4 cm
The volume of sphere = \(\frac{4}{3}\) x \(\frac{22}{7}\) x (1.4)3 = 11.50 cm3
