Answer:
150,000cm^3, or 1,500m^3
Explanation:
The question is basically asking the volume of this rectangular tank. 
The formula to find the volume is length x width x height. 
This is because we're trying to find the area of the base (length x width), and then we're multiplying the base times the height, to get how much of the base area can fit in the height of the rectangle.
So, the answer is 100cm x 50cm x 30cm = 150,000cm^3, or 1,500m^3, because 1 meter = 100 centimeters.
 
        
             
        
        
        
Answer:2 the lupine dependent butterflies would disappear.
If the spraying of pesticides will remove all the insects then there will be no insect that will pollinate the lupine flowers. So this will cause removal of lupine species from the environment. And the lupine dependent butterflies will not be able to release their egg on these specific flower and will also disappear from the environment. 
The removal of lupine flower from the environment will lead disappearing of these lupine dependent butterflies.
