Calculating Volume with Decimals

The video tutorial covers the concept of calculating volume using decimals. It begins with an introduction to volume and the importance of understanding decimal multiplication. The teacher provides multiple examples, each progressively more complex, to demonstrate how to calculate volume by multiplying length, width, and height. The tutorial emphasizes the importance of understanding place value and decimal alignment. The session concludes with a summary and a preview of the next lesson, which will focus on finding volume using fractions.
