Question: Unit cube:
What is the volume of the rectangular prism?
1. **State the problem:** We need to find the volume of a rectangular prism that is composed of unit cubes arranged 4 wide, 3 high, and 2 deep.
2. **Formula for volume of a rectangular prism:**
$$\text{Volume} = \text{length} \times \text{width} \times \text{height}$$
3. **Identify dimensions:**
- Length = $4$ units
- Width = $2$ units (depth)
- Height = $3$ units
4. **Calculate the volume:**
$$\text{Volume} = 4 \times 2 \times 3$$
5. **Multiply step-by-step:**
$$4 \times 2 = 8$$
$$8 \times 3 = 24$$
6. **Final answer:**
The volume of the rectangular prism is $24$ cubic units.
