How is depth of stone calculated?

Rectangle

1. Measure Length and Width (in feet)
2. Length x Width = square feet.
3. Determine desired depth of material (see recommended depths and chart below)
4. Square feet divided by sq.
5. Example: A rectangular area 16 feet long by 10 feet wide and you want 4 inches deep of stone.
6. Calculations:
7. 16 x 10 = 160 square feet.

How can you tell how high something is by dropping a rock?

It goes like this:

1. Toss a rock straight out from the cliff and use a stopwatch to time how long it takes to hit the water.
2. Multiply that number by itself, and then multiply that by 16.
3. That should be almost exactly the height of the cliff in feet.

Which unit is used to measure the depth of well?

A fathom is a unit of length in the imperial and the U.S. customary systems equal to 6 feet (1.8288 m), used especially for measuring the depth of water.

How do I figure out how many tons of rock I need?

Length in feet x Width in feet x Depth in feet (inches divided by 12). Take the total and divide by 21.6 (the amount of cubic feet in a ton). The final figure will be the estimated amount of tons required.

How do I figure out how much stone I need?

Multiply the length (L), in feet, by the width (W), in feet, by the height (H), in feet, and divide by 27. This will tell you how many cubic yards of crushed stone you need. When using this equation, make sure all of your measurements are in feet.

How do you find depth with area?

The area of a square or rectangular garden is easy to calculate. Simply multiply the length by the width by the depth or use our simple volume calculator.

How do you measure depth of a dropped object?

However, using physics it is possible to calculate the depth of the water because once dropped, the stone will accelerate due to gravity at a rate of 9.8 meters per second squared, and you can determine the distance it traveled by using the distance formula: D = v0​t + 1/2​a*t^2.

How do you calculate the depth of water when dropping a stone?

However, using physics it is possible to calculate the depth of the water because once dropped, the stone will accelerate due to gravity at a rate of 9.8 meters per second squared, and you can determine the distance it traveled by using the distance formula: D = v0_t + 1/2_a*t^2. Since the stone is being dropped, the initial velocity, v0, is zero.

What happens when a stone is dropped from top of well?

The stone is dropped from top of the well. The level of water in the well is say ‘h’ metre below the top of the well. When a stone is dropped from top of the well, it travels in air and then hits the top of water level in the well producing sound.

What does depth of the well mean?

Depth of the well means the distance between the bottom of the well and the top of the water level in the well. This question is wrongly worded. The stone is dropped from top of the well. The level of water in the well is say ‘h’ metre below the top of the well.

How fast does the water drop from a deep well?

Most wells are shallow so ignore the terminal velocity. The speed of sound is also fast enough to ignore in many cases. A 16 foot deep well will have a one second drop. A ~64 food deep well will have a two second drop.
