Final answer:
The question is related to Physics, focusing on the work required to pump water from a tank using fluid mechanics principles. Due to missing specific details, a step-by-step solution cannot be provided, but a general approach involves calculating volume, weight, and multiplying by the pumping height.
Step-by-step explanation:
The subject of the student's question is Physics, specifically related to fluid mechanics and the concept of work done in pumping fluids. The question involves calculating the work required to pump water out of a tank, considering the weight of water per cubic foot is 62.5 lbs. To calculate this, we would need to know the dimensions of the tank, the height of the water, and the height the water needs to be pumped to. However, as this information is not given in the snippet, we cannot give a step-by-step solution. Generally, you would calculate the volume of water that needs to be displaced, convert this to weight using the given density, and then multiply by the height to which it needs to be pumped to find the work done, taking into account gravity. Remember to use consistent units throughout the calculation.
