It can hold about 179.07 cubic inches more of water.

Volume = pi r^2

The volume of the water in the 8 inch glass = 8 pi (1.5)(1.5) = 18pi = about 56.55 cubic inches

The volume of the 12 inch glass = 12 pi (2.5)(2.5) = 75 pi = about 235.62 cubic inches

The difference in volume is 57 pi or about 179.07 cubic inches

*previous answer used a different size glass
