Yes, the depth of a manhole can be calculated by subtracting the invert level (the lowest point inside the manhole) from the cover level (the ground level above the manhole). This difference gives the vertical distance from the cover to the invert, which represents the depth of the manhole.

Rim, on a manhole, is the elevation of the top of the cover on the manhole. In a roadway the rim will at be final grade, in grass they can be sumped, flush or stick up.

"Manhole covers" are simply spelled "manhole covers". The reason most of them are perfectly round is that a round cover cannot slip down into a hole that is even just slightly smaller than the cover (as can oblongs or squares).
A typical manhole cover can weigh between 90 to 300 pounds depending on its size and material.
Manhole covers are used for many things. Manhole covers are used to cover up holes in the ground where sewage can be found in order to protect people.
The manhole is at Main Street by the Muesuem.

To calculate the number of manhole rings needed to reach cover levels, you first need to determine the desired cover level. Then, measure the height of each manhole ring and divide the desired cover level by this measurement to find the number of rings required. Round up to the nearest whole number to ensure proper cover level.
