The sand give the cement in the mix something to hold on to. It gives the mortor strengh by connecting all the grains together. The cement to sand is pretty much the same principal as mortar to brick. Joining the pieces together to create a whole.
A brick of sand be used
a lot , but depends on the size of it and if a sand castle none :)
To calculate the amount of sand and cement needed for 2000 bricks, you first need to determine the volume of one brick. Assuming a standard brick size of 8 inches by 4 inches by 2 inches, the volume of one brick is 64 cubic inches. For 2000 bricks, the total volume would be 128,000 cubic inches. To convert this volume to cubic feet (since sand and cement are typically measured in cubic feet), you would divide by 1728 (12x12x12). This gives you approximately 74.07 cubic feet of sand and cement needed for 2000 bricks.

Whether or not you need to use sand as a base in laying a sidewalk depends upon what you are laying it with. For example, if you were using bricks, it would be better to use a sand base to prevent the bricks from shifting over time.
The best type of sand to use for laying under pavers is coarse sand. It provides a stable base and allows for proper drainage.
sand stone/brick
not a lot. but assuming 9"x3" and using this brick calculator it works out at 0.0003 cubic meters of mortar or 0.91kg of sand and 0.25kg of cement per brick.
