This answer is unlimited. All sponges are different sizes, and each species has variations on the number of pores. Sponges are only made of spongin, a network of webbed collagen. Pores are only gaps in the spongin where water is forced through. As you may already know, squeezing a sponge expels the water from all locations of the sponge. Therefore, water can travel through all parts of the sponge. You may consider every gap in the spongin to be a pore. This number cannot be recorded, as it varies greatly throughout all sponges.
