How to Find Volume – Basic of Geometry
In this article, let us start to look at the relationships of the 3-dimensional and 2-dimentional equivalents of the area and perimeter to be able to deeply know the ways on how to find the volume.
Again, do not let Mathematics or geometry in particular scare you into knowing this. The method in finding the volume, say a cube is not that hard. It takes the same methods just like how you find other volume of other shapes.
But before we further explain the method or formula of finding the volume, let’s try to understand the real meaning of volume. What is volume? This is the term for the amount of space taken up by an object or shape. Solving the volume of an object may need you to compute for the length, width and height.
Let us take cube as our example. As always, we just have to be sure that you are familiar with the cube. This is similar like the Rubik’s Cube which is a 3-dimensional object where every side has the same length.
Every angle of this is right angle like that of the square. Remember these features as it will be your guide towards determining the way finding the volume. So okay, the best image to hold in your mind now of the cube is the Rubik’s Cube.
Now, let us define what a Volume is since we are in quest to know how to find the volume. It is a dimensional equivalent of area or the inside space. If you can remember your past lessons, the area is measured technically with squares being placed inside the object and counting how many of them are there.
In short, in order for you to see the 3-dimensional figures, you have to fill the cubes and count its numbers inside. But that is not just the case. There is a formula to make it easier. If our goal is to fill the area with cubes, there must probably be 90 cubes altogether. How is that so?
It could be thought of as 3 rows of 6 squares or 18 squares or since A = bh, A = 3 x 6 = 18 sq. inches. The cube here is 1 inch by 1 inch by 1 inch. Abbreviating it would result to 90 cu in or more mathematically, it is shown as 90 in^3.
Now as obviously, the way on finding the volume is to determine and have the exact formula as V=lwh. L stands for length, W for width, and H is for height. You can use this formula to any dimensions you want to search for volume.
Just you make sure that you will adjust the sides that have the same length to make the calculations easier. Begin with the tissue box as you example for the side formula determination. The challenge is on.
