体积

The Chinese word 体积 (tǐjī) for "volume" is composed of two characters: 体 (tǐ) and 积 (jī). 体 originally meant "body" or "substance", and later extended to mean "volume" or "capacity". 积 originally meant "to accumulate" or "to gather", and later extended to mean "volume" or "amount". The combination of these two characters creates the word 体积, which specifically refers to the volume of a three-dimensional object.In terms of etymology, the character 体 is derived from the oracle bone script, which depicts a person with a large belly. The character 积 is derived from the oracle bone script, which depicts a hand holding a bundle of sticks. Over time, the shapes of these characters have evolved into their current forms, and their meanings have also expanded to encompass a wider range of concepts.The word 体积 is commonly used in various fields, including physics, mathematics, and engineering, to refer to the amount of space occupied by a three-dimensional object. It is an important concept in understanding the properties and behavior of matter, and plays a crucial role in calculations and measurements related to volume.
