The formula for finding the volume of a rectangular pyramid (as you said that it has a rectangular base, which means that it is a rectangular pyramid) is: 

l x w x h divided by 3 

so substitute the given: 

25 x 18 x 20 divided by 2 

=3000 cm³ (cubed because its the volume)

So,  L x W x H ÷ 3

V = 25 X 18 X 20 

V = 9000 ÷ 3 

V = 3000 cm^3
