Volume Calculations and Conversions

Nancy ET Johnson 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 converts these measurements to feet and demonstrates how to calculate the volume of a rectangular prism by multiplying the width, height, and depth. The video concludes with the final volume calculation and a brief explanation of the result.
