Answer:

Volume of head = 1000 cm^3

Explanation:

The head of a normal person can be assumed as a sphere with radius 10 cm.

Volume of sphere $=\frac{4}{3} \pi r^3$ , where r is the radius.

We have approximate radius = 10 cm.

Approximate volume of head $=\frac{4}{3}* \pi *10^3=4189 cm^3$

In the given options the closest value to the approximate volume is 1000 cm^3.

So, volume of head = 1000 cm^3
