1/8 of a sphere with radius of 6.12 (all equil wedges)

The formula for the volume of a sphere is V=4/3*pi*r^3

So, V=4/3*pi*6.12^3

4/3*pi = 4.188790204786391

Now, multiply that by 6.12^3

4.188790204786391*6.12^3 = 960.158377938446586790848, so V≈960.16

Now, divide that by 8.

960.16/8 = 120.02, so each eighth equals 120.02 units³.

There we go! 

Good job, Rarinstraw.....!!!!
