Answer:
1. (top left corner) = 8km^3
2. (bottom left corner) = 243 in^3
3. (top right corner) = 200 cm^3
4. (bottom right corner) = 3165.12 m^3
Explanation:
1. (top left corner) lwh = 4km x 2km x 1km = 8km^3
2. (bottom left corner) (lwh)/3 = (9 x 9 x 8) / 3 = 243 in^3
3. (top right corner) lwh = 5 x 5 x 8 = 200 cm^3
4. (bottom right corner) πr^2h
R = 12
3.14 x 12^2 x 7 = 3.14 x 144 x 7 = 3165.12 m^3
