Changes to Volume and Surface Area
In this video, we investigate how changing the linear dimensions of a 3d solid will affect the volume and surface area. After a dilation of a certain scale factor, how can that scale factor be used to predict the new volume or surface...

Dimensional Change 3 (advanced applications)
In this video, we investigate how changing the linear dimensions of a three dimensional solid affects the volume and surface area. Specifically, how do we solve for missing values (like side length, volume and surface area) when we are...

Dimensional Change 2 (practice and applications)
In this video, we practice calculating how volume and surface area would change as we change the linear dimensions of 3d figures.

The Determinant | Essence of Linear Algebra, Chapter 5
Determine how much a linear transformation alters area. The seventh segment in a series of 15 makes the connection between the determinant and the scale factor of areas during a linear transformation. The video goes on to explain the...
