Volume and Dimensions of Prisms

This video tutorial covers the calculation of the volume of rectangular prisms, focusing on converting mixed numbers to fractions for easier computation. It provides examples of calculating volume using fractions and compares the volumes of cubes with different side lengths. The tutorial also explains how to determine the number of smaller cubes needed to fill a larger prism and concludes with solving for unknown dimensions using given volume, height, and length.

What is the formula used to calculate the volume of a rectangular prism?

• Length + Width + Height

• Length × Width × Height

• Width × Height

• Length × Width

How do you convert a mixed number to an improper fraction?

• Multiply the whole number by the denominator and add the numerator

• Add the whole number to the numerator

• Multiply the numerator by the denominator
