The volume that needs to be filled is 11 x 45 x 0.5 = 247.5 cubic feet, say 250.There is a lot of info if you google pea gravel weight. The most frequent weight I saw in those postings was about 100 lbs per cubic foot. So the weight of 250 cuft of pea gravel is about25,000 lbs or 12.5 tons.
One yard of PEA Gravel weighs approximately 3,000 pounds Clarification: one CUBIC yard weighs approx 3,000 pounds.
1 cubic yard = 27 cubic feet = 54 half-cubic-foot bags

First, you need the density of pea gravel. This depends heavily on particle size and cleanness of the gravel, but a density of 3000lb/yard3 is a realistic estimate. If you want the final answer in metric, it's useful to convert the density to 1780kg/meter3. Knowing this density, you can use it as a conversion factor. You just take the mass of your Pea gravel (for example 50kg) and multiply it by 1 meter3/1780kg to make the units cancel out. Or if you want it easy, just take the weight of your pea gravel in kilograms and divide it by 1780 to get volume in cubic meters. This is a very rough estimate, and actual values depend on the density of the pea gravel being used. The basic idea for any conversion is that you get the density and make sure it uses cubic meters.
Each .5 cubic feet bag of pea gravel will weigh approx. 50lbs.
1 cubic yard = 1.3 tons
The average cubic meter of pea gravel weighs 1788 kilograms. A cubic meter weighs approximately 1.79 tonnes, and a square meters only weighs 17.88 kilograms or 9.3 pounds.

It would obviously depend on how thickly you wanted to cover the surface, and how 'tall' a single unit of pea gravel was. You would need 736 bags per foot depth.
