How many steel will be used in one culvert?

Answer is simple “quantity of steel is different in different structural elements because load (tensile force) taken by different element are different”.
Eg:- Load (tensile force) on beam is slightly greater than load on slab so, steel quantity in beam is slightly more than slab. Likewise in every structural elements.
Therefore,
Slab /lintel——0.7 to 1.0% (55 to 78.5kg)/m^3
Columns_______0.8 to 6.0% (62.80 to 471kg)/m^3
Beam __________1.0 to 2.0% (78.5 to 157kg)/m^3
Foundation____ 0.5 to 0.8% (39.25 to 62.80)/m^3
Note:- In most cases we do not go beyond 4%(314kg/m^3) reinforcement in Column because”it will become difficult to pour concrete and compact it”.

Quantity of steel is not dependent on the volume of concrete, but on the structure where it is being used.
Slabs: 0.7 to 1.0%,
Beams: 1% to 2%,
Columns: 1% to 5%
It may vary depending upon the loading condition as well
For Example
Lets take example of RCC Column, where reinforcement required is 2 % of concrete volume, weight of steel required will be:
(2/100*1)*7850 (steel density )-per m3 steel-157 kg
However if you require an approximate value, then we can follow thumb rule for steel requirement that provides a rough value of Steel quantity per M3 used
Footing - 80 kg/cumec
column - 160 kg/ cumec
Beam - 110 kg/ cumec
slab - 80 kg / cumec
P.s : the thumb rule is just an appr. value given taking into task of normal dimension of structure provided. its always better to go through design calculation

Thanks for the ask, but this is not something I know much about.
I think you are asking about the rebar, reinforcing rods, used in pouring concrete.
If so, this is determined either by building code in your area, or the specific engineering required to support your design.
You need a bit more clarity in your question, and either an engineer or a concrete speciallist to get a solid answer.
