How do I convert cubic yards to cubic meters?

Thanks.

If you have a box with side lengths A, B, and C, then the volume 
of the box is A*B*C.

A cubic yard is a box with sides all 1 yard long, so the volume 
of a cubic yard is (1 yard)*(1 yard)*(1 yard).

To convert yards to metres, 1 yard = 0.9144 metre. Therefore, 
a cubic yard is (0.9144 metre)*(0.9144 metre)*(0.9144 metre), 
which is 0.9144*0.9144*0.9144 (1 metre)*(1 metre)*(1 metre).

But (1 metre)*(1 metre)*(1 metre) is a cubic metre for the same 
reason that (1 yard)*(1 yard)*(1 yard) is a cubic yard.
This means a cubic yard is 0.9144*0.9144*0.9144 cubic metre.
I'll leave it to you to multiply 0.9144*0.9144*0.9144.
