Let’s go through each box one by one and calculate the volume.
Volume of a rectangular prism (or cube) is found by multiplying:
Length × Width × Height
We’ll do this for each shape, using the numbers given on the sides.

First row:
1. Box with sides 4cm, 3cm, 6cm
→ Volume = 4 × 3 × 6
→ 4 × 3 = 12
→ 12 × 6 =
72 cm³
2. Box with sides 8mm, 2mm, 3mm
→ Volume = 8 × 2 × 3
→ 8 × 2 = 16
→ 16 × 3 =
48 mm³
3. Cube with all sides 5cm
→ Volume = 5 × 5 × 5
→ 5 × 5 = 25
→ 25 × 5 =
125 cm³

Second row:
4. Box with sides 5m, 4m, 4m
→ Volume = 5 × 4 × 4
→ 5 × 4 = 20
→ 20 × 4 =
80 m³
5. Box with sides 5cm, 2cm, 8cm
→ Volume = 5 × 2 × 8
→ 5 × 2 = 10
→ 10 × 8 =
80 cm³
6. Tall box with sides 3m, 3m, 10m
→ Volume = 3 × 3 × 10
→ 3 × 3 = 9
→ 9 × 10 =
90 m³

Third row:
7. Box with sides 7cm, 4cm, 5cm
→ Volume = 7 × 4 × 5
→ 7 × 4 = 28
→ 28 × 5 =
140 cm³
8. Cube with all sides 4mm
→ Volume = 4 × 4 × 4
→ 4 × 4 = 16
→ 16 × 4 =
64 mm³
9. Box with sides 8m, 2m, 4m
→ Volume = 8 × 2 × 4
→ 8 × 2 = 16
→ 16 × 4 =
64 m³

All calculations check out. Each volume is correctly calculated by multiplying the three dimensions together, and units are kept consistent (cm³, mm³, or m³ depending on the original measurements).
Final Answer:
The volumes are:
72 cm³, 48 mm³, 125 cm³,
80 m³, 80 cm³, 90 m³,
140 cm³, 64 mm³, 64 m³
