![]() There is a good reason for this it will help you better understand how you calculate the volume of a cube. In true dad style, we will teach you how to do things the old-fashioned way before you move into the future. We will first calculate the volume of a cube by hand, and later we will use the Omni-Calculator to find the volume of a cube without having to deal with the formula at all. Now that we have seen and understood the cube volume formula, we shall move on to explaining how to calculate the volume of a cube. If you are happy enough with the current difficulty level, let's move on. These are more complicated and will probably make you happier. If all this sounds very easy to you, just know that there are other formulas for the volume of a cube in case you don't know the length of the sides. Like how you calculate the area of a square by multiplying the length of each side, you can multiply the three sides of a cube since they are all the same. The previous formula comes from the fact that the cube volume (in 3D) is analogous to the area of a square (in 2D). This is just another way to say that you need to multiply the length of each side l by itself three times: l × l × l = l³, or, in other words, elevating it to the third power (learn more about power in the exponent calculator) ![]() Where l is the length of the sides of the cube. But if you are not interested in abstract concepts and just want to know the volume of a cube, there is a simple answer to the question What is the volume of a cube? It has a turns ratio of 10:1 on the 100% tap.Volume is a measure of the 3D space occupied by an object.When the taps are in the primary winding, the new turns ratio can be calculated by multiplying this percentage by the full turns ratio:.The tap percentages indicate the percentage of the full turns that are effective when the tap is used.Any decrease in the number of turns in the primary will increase the volts per turn ratio, thus increasing the secondary voltage.Any increase in the number of turns in the primary will reduce the volts per turn ratio, thus lowering the secondary voltage.Some transformers provide taps to do that. To compensate for the line drop, it would be lovely if we could reduce the turns ratio of the transformer to 9.5:1. ![]() With the 10:1 turns ratio on the transformer, the secondary voltage is 105 V. ![]() This means that the terminal voltage applied to the primary of the transformer is only 1050 V. Total line drop in the primary circuit is 150 V due to the volt drop across the resistance of the primary circuit (75 V+ 75 V). When current flows in the secondary circuit, things start to change. There is a potential secondary voltage of 120 volts but there is no current flowing in the secondary. In this example, the supply voltage and the terminal voltage will be the same value. 25Ω resistance in the primary is the resistance of the winding. For all intents and purposes, there is very little current flowing in the primary (in this case we will say it is negligible). In the image below, we have a transformer whose secondary is open. Some transformers compensate for line drop and percent voltage regulation by having multiple taps by which the volts/turn ratio can be adjusted.
