Convert the dimensions of the pool from feet to yards and then use the usual formula for calculating the volume of a box.

First of all the shape must be known although I will assume a cuboid

Either do what Mr F said or multiply your ft measurements and divide by 27

$V = \frac{1}{27}(25 \cdot 10 \cdot 6) = \frac{1}{9}(25 \cdot 10 \cdot 2)$
