Does air have mass?
The pressure at the bottom of the pitcher of water 35cm deep is higher than at the bottom of the bathtub of water 30cm deep. Pressure in a fluid increases with depth, so the deeper the water column, the greater the pressure at the bottom. This is due to the weight of the water above exerting a force on the bottom.

A typical gingersnap is round and flat, about an inch and a half across, and deep ginger brown.
15 foot round? About 5000 gallons, if it's four feet deep. Here's a formula for round pools: distance across*distance across*depth*5.9 for rectangles: length*width*depth*7.5 or for a deep end: length*width*((shallow end depth + deep end depth)/2)*7.5
A 100-foot round pool filled with 1.5 feet of water would be holding about 88,500 gallons.
A round pool 8 feet across and 18 inches deep holds up to 2,857.5 gallons of water.
Here's a formula for round pools: distance across*distance across*depth*5.9 for rectangles: length*width*depth*7.5 or for a deep end: length*width*((shallow end depth + deep end depth)/2)*7.5 so in your case, 21*21*4.3*5.9=11000 gallons

Here's a formula for round pools: distance across*distance across*depth*5.9 for rectangles: length*width*depth*7.5 or for a deep end: length*width*((shallow end depth + deep end depth)/2)*7.5 so in your case, 16*16*4*5.9=6000 gallons=23000 liters
Here's a formula for round pools: distance across*distance across*depth*5.9 for rectangles: length*width*depth*7.5 or for a deep end: length*width*((shallow end depth + deep end depth)/2)*7.5 so in your case, 18*18*4*5.9=7500 gallons
Here's a formula for round pools: distance across*distance across*depth*5.9 for rectangles: length*width*depth*7.5 or for a deep end: length*width*((shallow end depth + deep end depth)/2)*7.5 so in your case, 28*28*4.3*5.9=20000 gallons
A round swimming pool 12 feet across by 4 feet deep will hold 452 ft3 which converts to 3,381 gallons
