A water tank is in the shape of an inverted square pyramid. The pyramid is 10 ft tall and 24 ft wide at the top. How much work is needed to pump out the bottom 5 ft of water to the top of the tank? To simplify calculations, 1. use w for the weight density of water in lieu of 62.4 lb/ft 2. Solve only until you have integrated the definite integral and show the limits. No need to plug in the limits Place the origin at the center of the top of the pyramid.
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
