Depends on material.

1 cubic yard of crushed rock fills 3/depth in feet square yards.
About 35... there are 27cubic feet in one cubic yard so determine how many cubic feet you need and divide by 27... in your case 52x 18x 1= 936 cubic feet 936/27= 34.66 cubic yards
2.7T/m3 (+/- 10%). The above answer is for solid rock, generally not crushed stone. Crushed stone of uniform size has a nominal density of 100 pounds per cubic foot (1.6 Metric Tons per cubic Meter). If the crushed stone is a mixture of various sizes, then the open spaces that would be present in crushed stone of uniform size will be filled somewhat by the smaller sizes, and density increases. Typical effective density here ranges from 120 - 140 pounds per cubic foot (1.9 - 2.2 Metric Tons per cubic Meter). Solid Rock will be close to 150 - 170 pounds per cubic foot (2.4 - 2.7 Metric Tons per cubic Meter). Crushed stone density is variable depending on the type of stone, the stone crushing machinery, and how the crushed stone is sorted after crushing.
A little more than one cubic yard of crushed rock is needed. (10 ft x 6 ft x 1/6 ft = 10 cu ft = 1 cu yd + 1 cu ft)
Volume = (84) x (1/6) = 14 cubic feet = 0.52 cubic yard
No they are not. River rock is rounded and smooth where crushed rock is sharp and jagged.
What is differences between crushed rock and crushed sand
The texture.
This question needs to be quantified. If a solid rock was crushed and all the rock matter was contained to be measured after crushing the rock you find the there is no change in the amount of matter it simply changed from one rock to many. However if the question is will the rock take up more space after crushed the answer is of yes it would depending on how many pieces it was broken into.
1 cubic millimeter is a very small amount. it would be about the size of a grain of sand. That is my best guess.
Approx 0.45
