ANSWER:
I.
1-3. A = b × h
A = 10 cm × 16 cm
A = 160 cm^2
4-6. A = 1/2 × b × h
A = 1/2 × 4 m × 6 m
A = 12 m^2
7-10. A = 1/2 × (b1 + b2) × h
A = 1/2 × (12 cm + 20 cm) × 14 cm
A = 1/2 × (32 cm) × 14 cm
A = 224 cm^2
II.
11. The volume of a rectangular box.
12. 15 cm long, 12 cm wide and 10 cm high
13. Multiplication
14. V = L × W × H = N
15. V = 15 cm × 12 cm × 10 cm
V = 1,800 cm^3
- The volume of a rectangular
box is 1,800 cm^3.
