Exploring Packing with Unit Cubes

The video tutorial covers the concept of volume in geometry, focusing on calculating the volume of three-dimensional shapes using unit cubes. It begins with an introduction to volume and progresses to calculating volume using whole numbers and fractions. The tutorial also includes exercises on estimating how many small cubes fit into larger prisms and dividing volumes to find the number of cubes. Throughout the video, patterns in volume calculations are highlighted, and students are encouraged to practice these concepts independently.

What formula is used to calculate the volume of a rectangular prism?

• Volume = Length x Width / Height

• Volume = (Length + Width) x Height

• Volume = Length x Width x Height

• Volume = Length + Width + Height

How do you calculate the number of smaller cubes that fit into a larger prism?

• Divide the volume of the larger by the smaller
