Let’s solve each rectangular prism volume problem one by one.
Remember:
Volume of a rectangular prism = length × width × height
We’ll multiply the three given dimensions for each shape. Be careful with units — but since all dimensions in each problem use the same unit (cm, mm, or m), we can just multiply them and keep the unit cubed (like cm³, mm³, m³).

First row:
1. Dimensions: 4cm × 3cm × 6cm
→ 4 × 3 = 12; 12 × 6 =
72 cm³
2. Dimensions: 8mm × 2mm × 3mm
→ 8 × 2 = 16; 16 × 3 =
48 mm³
3. Dimensions: 5cm × 5cm × 5cm
→ 5 × 5 = 25; 25 × 5 =
125 cm³

Second row:
4. Dimensions: 5m × 4m × 4m
→ 5 × 4 = 20; 20 × 4 =
80 m³
5. Dimensions: 5cm × 2cm × 8cm
→ 5 × 2 = 10; 10 × 8 =
80 cm³
6. Dimensions: 3m × 3m × 10m
→ 3 × 3 = 9; 9 × 10 =
90 m³

Third row:
7. Dimensions: 7cm × 4cm × 5cm
→ 7 × 4 = 28; 28 × 5 =
140 cm³
8. Dimensions: 4mm × 4mm × 4mm
→ 4 × 4 = 16; 16 × 4 =
64 mm³
9. Dimensions: 8m × 2m × 4m
→ 8 × 2 = 16; 16 × 4 =
64 m³

All calculations checked twice. Ready to write final answers.
Final Answer:
Volume = 72 cm³
Volume = 48 mm³
Volume = 125 cm³
Volume = 80 m³
Volume = 80 cm³
Volume = 90 m³
Volume = 140 cm³
Volume = 64 mm³
Volume = 64 m³
