Calculating Volume of Rectangular Prisms with Fractional Edges

The video tutorial explains how to calculate the volume of a structure composed of 12 cubes, each with an edge length of 1/2 inch. The structure is a rectangular prism, and the volume is calculated by multiplying its length, width, and height. An alternative method involves calculating the volume of a single cube and multiplying by 12. The tutorial demonstrates both methods, simplifying fractions and converting improper fractions to mixed numbers.

How many cubes make up the structure?

• 14 cubes

• 8 cubes

• 12 cubes

• 10 cubes
