Determining Volume
The rectangular prism is constructed using ½-inch unit cubes.
Goal: Find the total volume by analyzing the unit cubes, then mapping it to the formula $V = l \times w \times h$.
1. Analyze the Unit Cube
"Each unit cube has side lengths of ½ inch. To find its volume, I multiply ½ × ½ × ½."

2. Pack the Prism
"The prism has 3 layers. Each layer holds 10 unit cubes. I need to find the total number of cubes."

3. Apply the Formula
Use the dimensions of the unit cube to find the prism's dimensions.
"Length is 5 cubes. 5 × ½ = 2 ½ in. Width is 2 cubes..."
Apply $V = l \times w \times h$ directly to the entire structure.
