For example:
The height of a cuboid is expressed by h, and the letter formula is V=lwh.
In mathematics, h sometimes represents the height of a plane figure. For example, the height of a parallelogram is represented by h, and the formula is S=ah.
The height of the triangle is expressed by H, and the letter formula is S=ah÷2.
Extended data:
1. In the international system of units, h stands for hecto, that is, 100 (10 2) stands for hours (time units) in the international system of units.
2.h In chemistry, hydrogen is a chemical element, ranking first in the periodic table of elements. The common elemental form of hydrogen is hydrogen. It is a colorless, odorless and easily combustible gas composed of diatomic molecules, and hydrogen is the lightest gas.
