Calculating Volume with a Ruler

The video tutorial explains how to use a metric ruler to find the volume of a rectangular solid. It begins by defining a rectangular solid and the importance of square corners. The concept of cubic centimeters is introduced, including its notation as cc or cm³. The tutorial then guides viewers on measuring the length, width, and height of an object, emphasizing the importance of measuring from one corner. Finally, it demonstrates the calculation of volume using the formula length × width × height and discusses the resulting units in cubic centimeters.

What is essential for an object to be measured using a ruler for volume?

• It must be flexible.

• It must be circular.

• It must have square corners.

• It must be a liquid.
