Calculating Volumes of Rectangular and Triangular Prisms

The video tutorial explains how to calculate the volume of rectangular and triangular prisms. It begins with an introduction to the concept of volume, emphasizing the use of cube units. The tutorial then details the process of calculating the volume of rectangular prisms by multiplying the area of the base by the height. It also covers the calculation of triangular prism volume, using the formula for the area of a triangle as the base. The video includes example calculations to illustrate these concepts.

What does volume measure in a 3D object?

• The amount of space the object occupies

• The perimeter of the object

• The surface area of the object

• The weight of the object

Why is it important to label your final answer with cubic units when calculating volume?

• All of the above

• To indicate the volume is measured in three dimensions

• To show that the calculation is complete

• To differentiate from area measurements
