Answers & Comments
1. Volume of rectangular box = length x width x height
V = 18cm x 9cm x 9cm
V = 1,458 cubic cm
2. Volume of pyramid = (1/3) x base area x height
V = (1/3) x 120sq.m x 13m
V = 520 cubic m
3. Volume of cone = (1/3) x volume of cylinder
V = (1/3) x 225cu.m
V = 75 cubic m
4. Volume of conical tent = (1/3) x π x radius^2 x height
V = (1/3) x π x 1.5m^2 x 2m
V = 4.71 cubic m
5. Volume of rectangular prism = base area x height
Base area of pyramid = (1/3) x base area of rectangular prism
Therefore, base area of rectangular prism = 3 x base area of pyramid
V = 3 x 65cu.m
V = 195 cubic m
