If 10000 J of work was done to raise a 250 kg box how high was the box raised?

if 10000J were used to lift it, it means the total mechanical energy is 10000J. At the very top, kinetic energy is 0 (0 velocity), so potential energy is at it's fullest.
Potential energy can be calculated using E = m*g*h
E = 10000J, m = 250kg, g = 10m/s2. Leaving h to be 4m

Technically, once you know the weight of the box and the height of the platform, you can state the amount of"work" or "energy" needed to raise the box onto the platform. But there's no such thing as the power "needed"to do the job.Power is just the rate of doing work. You can calculate the amount of work needed, but it doesn't matter whetherthe work is done slowly or fast ... with low or high power.
How high is one million dollars in one dollar bills If the stack of 100 one dollar bills is one inch?
First we need to see how many stacks of $100 dollar bills go in $1 million. So $1000000/100 = 10000 stacks. If each stack is 1 inch then the pile will be 10000 inches high. Since 1 foot = 12 inches this will be 833.3 feet high (1 decimal place)
