It depends on the weight. The work required in joules (kg*m2/s2) is equal to the force applied in newtons and the displacement, or distance, in meters.
Thus, for an object that weights 1 N (multiply the weight of the object by the gravitational acceleration, 9.81 m/s2 to transfer to newtons) will require 1 N * 3 m = 3 J.
Thus, the formula for work is:
W = Fd
"W" is the work done on the system.
"F" is the force in newtons
"d" is the displacement (or distance) of the object in meters.
Weight of a mass of 50 kg = [ m g ] = (50 x 9.8) = 490 newtons.Work = force x distance = 490 x 4 = 1,960 newton meters = 1,960 joules
You can lift a locomotive or a house with 1 psi, if the pressure is applied over a large enough area.

To lift a 950-N load 3 meters requires (950 x 3) = 2,850 joules of energy.The power is the rate at which the energy is delivered. It takes more powerto lift the load faster.The power used to lift this load is (2,850 joules) divided by (the number of seconds it takes),and the unit of the answer is watts.
200 newton-meters per second = 200 watts.

I believe it is approximately 1.13 cubic meters (1.13 litres will lift 1 gram; do the math.

A true spider can lift eight times its weight.
The weight that a mouse can lift will depend on its size. It is estimated that mice can lift things that twice their body weight.
The amount of work done is determined by an object's force times the displacement. In this case it is 28 Newton meters, or 28 Joules.
The work down is 10Nx3m= 30Nm( Joules).
