Answer:
Step-by-step explanation:
we know that
The smallest cube that could circumscribe the sphere has a length side equal to the diameter of the sphere
In this problem
The radius of the sphere is
The diameter of the sphere is two times the radius
so
The length side of the cube is
Remember that
The surface area of a cube is equal to the area of its six faces
so
substitute the value of b
Solution :
The term 'literacy rate' provides the ability of a person who is from a definite age group can read or write.
