30" x 12.5" x 19" = 7,125 cubic inches = 30.84 gallons (rounded)
Given enough time the entire ocean could be pumped through a half-inch pipe.

About 2,794 gallons of water.
you need more info than that. you will need to provide the length of the hose and the inside diameter of the hose to calculate the amount of water it will hold
1 half of a inch
A two inch pipe can hold 0.1632 gallons per foot. It takes slightly over 6 feet of two inch pipe to hold one gallon of water.
Half a gallon
The amount of weight a half-inch sheet of plywood can hold will depend on the grade and type of plywood, as well as the size of the sheet and how the weight is distributed. As a general guideline, a half-inch sheet of plywood can typically hold between 40-60 pounds per square foot when evenly distributed.
A 5-inch pipe will hold approximately 0.36 gallons of water per linear foot. This calculation is based on the formula for calculating the volume of a cylinder (V = πr^2h), where the radius (r) is half the diameter of the pipe (2.5 inches) and the height (h) is 1 foot.
A cylinder with these dimensions will hold up to 13.06 gallons of water.
