I would like to see 20 cubic yards on a tandem. I would hate to pay that overload ticket.
20 cubic yards
Need to know the specifics of the dump truck you had in mind. Tandem axle dumps in the company I work for... if they have a 'dirt tub' body, they can carry 16 cubic yards. The ones with the 'rock tub' dump bodies can carry 15 cubic yards.

How many cubic yards will my dump truck hold it is 16x5.5x8
Provided it's not a short tandem, 15 yards with a 'rock tub' dump body and 16 yards with a 'dirt tub' dump body are typical.
The amount of dirt a dump truck can hold depends on the size of the dump truck. The average tri axle dump truck can hold 12 cubic yards of dirt, and a quad axle can hold 14.
That depends on what type of dump truck, what type of commodity, how it is measured (by weight or by cubic yard), and the state laws regarding weight allowances. A Class 7 single axle dump truck can typically haul eight to ten cubic yards, or up to eight tons of payload. A tandem axle dump truck can typically haul 15 to 20 yards, and anywhere between 12 and 16 tons of payload, dependent on truck specifications and local laws.

Dump trucks typically don't haul liquid commodities, unless you're thinking of snow removal operations where they'll be outfitted with prewet or calcium chloride tanks. Even with that in mind, you need to remember that there are many different sizes of dump truck out there. 15 cubic yards is "typical" for a tandem axle dump truck.
That would be 16 yards.
It can vary, but usually 10 cubic yards.
