🔷 Formula for Volume of a Rectangular Prism:
$$
\text{Volume} = \text{Length} \times \text{Width} \times \text{Height}
$$
We’ll calculate the volume for each shape, making sure to include units.

1. First Row
####
Prism 1:
- Dimensions: 4 in × 3 in × 6 in
$$
V = 4 \times 3 \times 6 = 72 \text{ in}^3
$$
####
Prism 2:
- Dimensions: 8 ft × 2 ft × 3 ft
$$
V = 8 \times 2 \times 3 = 48 \text{ ft}^3
$$
####
Prism 3:
- Dimensions: 5 in × 5 in × 5 in (This is a cube)
$$
V = 5 \times 5 \times 5 = 125 \text{ in}^3
$$

2. Second Row
####
Prism 4:
- Dimensions: 5 yd × 4 yd × 4 yd
$$
V = 5 \times 4 \times 4 = 80 \text{ yd}^3
$$
####
Prism 5:
- Dimensions: 5 in × 2 in × 8 in
$$
V = 5 \times 2 \times 8 = 80 \text{ in}^3
$$
####
Prism 6:
- Dimensions: 3 ft × 3 ft × 10 ft
$$
V = 3 \times 3 \times 10 = 90 \text{ ft}^3
$$

3. Third Row
####
Prism 7:
- Dimensions: 7 yd × 4 yd × 5 yd
$$
V = 7 \times 4 \times 5 = 140 \text{ yd}^3
$$
####
Prism 8:
- Dimensions: 4 ft × 4 ft × 4 ft (Cube)
$$
V = 4 \times 4 \times 4 = 64 \text{ ft}^3
$$
####
Prism 9:
- Dimensions: 8 in × 2 in × 4 in
$$
V = 8 \times 2 \times 4 = 64 \text{ in}^3
$$

✔ Final Answers:
| Prism | Volume |
|------|--------|
| 1 | 72 in³ |
| 2 | 48 ft³ |
| 3 | 125 in³ |
| 4 | 80 yd³ |
| 5 | 80 in³ |
| 6 | 90 ft³ |
| 7 | 140 yd³ |
| 8 | 64 ft³ |
| 9 | 64 in³ |

📝 Explanation:
- Always multiply the three dimensions: length × width × height.
- Make sure to keep the
units consistent and include the unit
cubed (e.g., in³, ft³).
- The shapes are not to scale, so trust the labeled measurements.
