At about the 4:09 mark, the teacher says each one of these slices has an area of 6; he should have said they have a volume of 6.
In this lesson, the instructor teaches how to find the volume of a triangular prism. First, they explain what a prism is and how it has two bases. Then, they demonstrate how to find the area of the base of a triangular prism by multiplying the base by the height and dividing it by two. After finding the area of the base, they explain how to calculate the volume of the prism by multiplying the area of the base by the height. The instructor provides a clear and concise explanation with helpful examples.
