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[tex]=\frac{4}{3} \pi r^3[/tex], where r is the radius.
 We have approximate radius = 10 cm.
 Approximate volume of head [tex]=\frac{4}{3}* \pi *10^3=4189 cm^3[/tex]
 In the given options the closest value to the approximate volume is 1000 cm^3.
 So, volume of head = 1000 cm^3
