Elevation of point + whatever reading from Meter Rod= HI
A ruler.
21cm and 16cm.what is the difference in height?
To calculate volume simply do length x width x height
Messure it,
The height and longer diagonal do not provide enough information to calculate the sides.
The ceilometer instrument.
How can you calculate height of airport traffic control tower?
A heightometer.
A ruler.
Of what?
Direct Measurement: Apply the instrument directly to the unknown quantity. E.g. Taped distance, direction measured with a theodolite Indirect Measurement: Determined from its relationship to direct measurements. E.g. height difference determination in trigonometric leveling
21cm and 16cm.what is the difference in height?
You just cube the height....like height to the 3rd power (height*height*height)
When surveying using a "level" instrument , the "level" instrument is set-up and adjusted to level by adjusting the screws. When surveying you have an instrument person and a rod person. When trying to find the height of the instrument, the rod person places there rod over a "known" elevation, either a benchmark or a temporary benchmark that has a known elevation. To get the height of the instrument, you need to "shoot" the level to the rod person holding the rod on the known elevation, this is called the "Backsight". This elevation will be read by the instrument person, and recorded in the survey field book. This value backsight elevation will then be added to the known elevation of the benchmark or the temporary benchmark, to get the height of instrument. HI = known elevation + BS Height
