My answer could be wrong but I got 58 N
Because your feet are not accelerating, the force exerted by the floor upon your feet must be exactly the same as the force exerted by your feet on the floor. If you are standing, the amount of force exerted by your feet, and thus the amount of force exerted by the floor, is equivalent to your weight.
a 500lb force moving through 6 feet does 3,000 foot-lbs of work.
Yes, the force exerted by the floor on our feet is equal to the force that our feet exerted on the floor, or it just depends on your weight, If you are heavier than the normal. When you stand, the longer the time you stand, the more pain you feel on your feet. And we can't be move upward by the force that the floor exerted on our feet because of the force of our weight that keeps us on the ground, and also because of gravity.
It is much lighter.
m20 grade concrete per m3 load
How much concrete is required to fill 100 cu feet
The depth of the pour would also be necessary to calculate the volume of concrete needed.

96 cubic feet of concrete
Depends where you are living.
about 17 yards of concrete (it's sold by the cubic yard)
It depends how thick you want it
3 cubic feet of it.
128
A cubic foot of concrete weighs ABOUT 150 pounds. 4 feet by 12 feet by 4 feet is 192 cubic feet. If you meant 4 feet by 12 feet by 4 INCHES, that would be 16 cubic feet.
About 4 feet
you would need 37.33 yards of concrete or 38 to be safe
