new pits are 300 feet apart. If all the test pits show sand and gravel, it is assumed that the entire area, 300 feet by 300 feet contains sand and gravel. Test pit E is excavated but no sand and gravel are found. This means the gravel deposit ends somewhere between B and E. It can be assumed the gravel material stops halfway, or in this case, 150

Sand vs. Gravel for Backfill: Which Is Right for Me?
You can use sand or gravel for backfill, as both are easy to use. They both discourage weeds from growing there, and they don't take a lot of maintenance to look great. Backfilling is the technique of filling those holes all the way in, and you can use sand, gravel, or other materials for it.

Concrete
The cement reacts with the water through a process called concrete hydration that hardens over several hours to form a hard matrix that binds the materials together into a durable stone-like material that has many uses. [8] This time allows concrete to not only be cast in forms but also to have a variety of tooled processes preformed.

When sand is added to water, it settles down at the bottom of the container because sand is heavier than water and insoluble in water (heterogeneous mixture).
