Answer:
Around 100,i.e. 105
Step-by-step explanation:
In the given cube 
Length of the cube = 7 unit cells 
Breadth of the cube = 3 unit cells
Height of the cube = 5 unit cells
Therefore the number of unit cubes required to make such big cube is nothing but the volume of the big cube = length*breadth*height 
⇒Number of cubes used to make that big cube= 7*5*3
                                                                                = 105
Hence, option D (around 100) is the correct answer
 
        
             
        
        
        
I think its 900
 because I did 12x3 for each day and then that gave me 36 then I did 36x25 cause there's 25 kids which gave me 900
        
                    
             
        
        
        
Answer:
x+y+2=-5 -2x-y+2=-1 x-2y-2=0 solve algebraically
x+y+2=-5     equation 1
-2x-y+2=-1    equation 2
x-2y-2=0      equation 3
Add equation 1 + 2+ 3
x+y+2=-5 + -2x-y+2+1 + x-2y-2
x+y+2= -7+2+1-2x+x+y
x+y+2= -4-x+y
x+y+2+4+x-y= 0
2x+6= 0
2x= -6
divide both side by 2
x= -3
from equation 1 insert x
x+y+2=-5
since x=-3
then, -3+2+y= -5
-1+y= -5
y= -5+1
y= -4
