The size of the cardboard should be  
Step-by-step explanation:
The diagram for this question is shown on the first uploaded image 
      The volume of the box is  
The length and the Width of the card is  
       L = W = Z
From the question we are told that 7 in squares were cut from each corner 
So the length and the width of the box  would be  
               L = W = (Z - 7)
And the height would be  H  =  7 in 
 Mathematically the volume of the box can be represented as 
               
So the Volume would be 
           
 
Substituting values 
          
            
  
           
=>

Dang he part of 20m trees? And is Alex a he or she, we'll never know, so I'll just refer to Alex as "it" to not gender appropriate anyone. 
So it gets paid 2.25 for one tree. It planted 437 tress. 
We take 2.25 x 437 to know the amount of money earned for all trees it planted. 
The answer is $983.25, or A. I don't want to gender appropriate the letter "A" either because it could be option 1 or a different letter so I'll just say the answer again to not be sexist, $983.25
