Answer:
4a2
Step-by-step explanation:
For a cube the lateral surface area would be the area of the four sides. If the edge of the cube has length a, the area of one square face Aface = a ⋅ a = a2. Thus the lateral surface of a cube will be the area of four faces: 4a2.

Answer:
23.7m
Step-by-step explanation:
Given parameters: 
        Time taken = 2.2s 
      Acceleration due to gravity = 10m/s 
Unknown: 
Depth of the well  = ? 
Solution: 
To solve this problem, we simply apply one of the motion equations;
         S = ut +  gt²
 gt²
     where S = depth of the well 
                 u = initial velocity 
                 t = time taken 
                g = acceleration due to gravity
  Input the parameters and solve for S;
    Note initial velocity = 0;
      S =  x 9.8 x 2.2²
 x 9.8 x 2.2²
      S = 23.7m
 
        
             
        
        
        
let's say the bill without the tip is "x" amount, so that'd be the 100% of the bill, but we also know that 4.50 is the 18% of "x".
so if 4.50 is the 18% of "x", how much is "x"?

 
        
             
        
        
        
To find the difference in weights from two years ago, you will need to combine the 2 differences from the two years.  
-1.56 and 0.73 becomes -1.56 + 0.73.
To add a positive and a negative number you will subtract the absolute values of the numbers AND use the sign of the number with the bigger absolute value (negative) in your answer.
|-1.56| - |0.73|
1.56 - 0.73 = 0.83
-0.83
The cat lost 0.83 (-0.83) pounds over 2 years.
