L*W*H stands for length, width, and height. It is a mathematical formula used to calculate the volume of an object or space. The formula works by multiplying each dimension together (length x width x height). For example, if you have a box that is 2 feet long, 3 feet wide and 4 feet tall, then the calculation would be: 2 ft x 3 ft x 4 ft = 24 cubic feet. This means that the total volume of your box is 24 cubic feet. L*W*H can also be used to measure irregular shapes such as cones or spheres. In this case, it may require some additional calculations in order to accurately determine the volume of these objects. Additionally, it can also be used when estimating how much paint you need for a wall or how much soil you need for a garden bed; simply multiply all relevant measurements together and voila – you have your answer!
