Calculating Volume and Density

In this video, Mr. Taylor explains how to find the density of a rectangular prism. He begins by introducing the concept of density and the necessary components: mass and volume. The video then demonstrates how to calculate the volume of the prism using its dimensions and a ruler. Next, Mr. Taylor shows how to measure the mass using a triple beam balance. Finally, he calculates the density by dividing the mass by the volume and provides a memory trick to help remember the formula. The video concludes with a teaser for the next episode, which will cover finding the density of a liquid.

What is the main objective of this lesson?

• To calculate the area of a rectangle
