Well, imagine you have a cube, like a dice. It has six sides, just like a dice. Now, let's say you want to measure how big it is. To do that, you need to know its volume, which is how much space it takes up.
To find the volume of a cube, you need to measure one side and then multiply it by itself two times (also known as "cubing" it). For example, if one side of the cube is 2 centimeters long, then its volume would be 2 x 2 x 2 = 8 cubic centimeters.
So when we talk about something being in cubic form, we are referring to a shape that has equal sides and can be measured using this same formula. It's kind of like a cube-shaped box.
Cubic forms can be found in many things, like ice cubes, building blocks, and even in math equations. They are pretty cool because they always have the same ratio of sides, which makes them predictable and easy to work with.
