Answer:
The correct answer is the number in the note is 80 and the first digit is 8.
Step-by-step explanation:
Dr. Green finds a note from another scientist. It says how many boxes of bug nets they should bring, but there is a smudge over the first digit of the number.
Number of nets that they must bring is 320.
Each box contains 4 nets.
There number of boxes necessary to be brought is given by  = 80.
 = 80.
Therefore the missing digit of number the number in the note is 8.

Not sure if there're any answer choices of some sort, 
but if the angle a and angle b are supplementary, that means when you add their measures together they must equal 180.
 
        
             
        
        
        
The volume of a cube is side^3
Volume = 11^3 
Volume = 1,331 cm^3
