The mean radius of the earth is approximately 6.4 million meters.
(4/3) x 3.14 x 64000003 m3
That's just the radius...after filling it all in and doing the math,
it comes to 1,097,509,500,000,000,000,000 cubic meters, solid, with the oceans.

The diameter of earth is 142800 km
Radius is therefore 81400 km
Volume of a sphere = 4/3 x pye r cubed
V = 1.333 x 3.142 x 81400 cubed
v = 4.1893 x 5.39353 x 10 to 17
v = 2.25924 x 10 to 18 km cubed
volume of earth is = 2,259,240,000,000,000,000 km cubed
As its not a perfect sphere this does not give the exact asnwer but give a good idea.
Sorry I can't type mathematical formulae in this box

v = 1/6 8* pi * D cubed =4.189 R cubed
v = volume
pi = approx 3.14159
D = diameter
r = radius
cubed means to multiply r * r *r
figure it out
