Volume Calculations in Cubic Feet

Nancy ET Johnson, a mathematics teacher, explains how to calculate volume in cubic feet. She begins by defining a cubic foot and describes the dimensions of a box in inches. She then demonstrates how to convert these measurements to feet and calculate the volume of a rectangular prism using multiplication. The video concludes with a summary of the process and the importance of understanding volume in cubic feet.
