Character Breakdown

Understanding 体積 (たいせき)

The word 体積 refers to the physical volume or capacity of an object or substance. It is commonly used in scientific, engineering, and everyday contexts when discussing how much space something occupies.

Usage and Context

体積 is often used when measuring liquids, solids, or containers. For example, you might ask about the 体積 of a box, a bottle, or a room. It is a neutral, formal term suitable for both casual and technical conversations.

Common Collocations

  • 体積を測る (たいせきをはかる): to measure volume
