Bob's hardware sells buckets in five different sizes.
The tiny bucket holds 3 quarts,
The small bucket holds 6 quarts,
The medium bucket holds 12 quarts,
The large bucket holds 24 quarts and
There is a relation between the size of the bucket and its volume.
We could see with increase in size the units of quarts double
Therefore the extra large bucket will hold 24*2 = 48 quarts
