Step-by-step explanation:
1. length ×breadth ×height
12× 6 ×3= 216
2. A is the area of the base, h is the height
18×16=288
3.10×14×5=700
Answer:
21. 216m^3
22. 4071.5m^3
23. 700m^3
21. V = L*W*H
V = 3*6*12
V = 216
22. V = [tex]\pi r^{2} h[/tex]
The diameter is 18 so the radius is 9
V = [tex]\pi[/tex](9^2)(16)
V= 4071.50408
23. V = L*W*H
V= 10*5*14
V=700
