Volume = 900 sqft * 1/12 ft = 75 cubic feet.
I need to know how thick the layer of gravel is meant to be.
It depends how thick the gravel is being laid - at 4 inches thick, a cubic yard will cover 81 square feet.

This question is incomplete. How thick it is expected to be put on. Is it being applied to currently black-topped area or on gravel. If this is for your own purpose of a driveway, check with a professional.
You have not said what substance you are using a ton of to cover the asphalt.

That depends on the size of the gravel and how thick a layer you want to end up with.
To cover 300 square feet 4 inches thick, you would need approximately 3 cubic yards of gravel.

The amount of gravel needed to cover 252 square feet depends on how thick (that is, deep) you want the gravel. If you want the gravel to be 3 inches thick... Convert the measurement to the same units. We'll use feet. 3 inches = 1/4 foot Multiply the thickness times the area to get volume in cubic measure. 1/4 feet x 252 feet = 63 cubic feet Gravel in the US is usually sold by the cubic yard, which is 27 cubic feet Thus, 63/27 = 2 1/3 cubic yards 2 1/3 cubic yards of gravel will cover 252 square feet of area to a dept of 3 inches.
It would take roughly 66 bags to cover a 200 square ft area 2 inches thick
20 mm = 0.020 meters 18 square meters * 0.020 meters = 0.36 cubic meters

It would depend on how thick you want to spread it.
