Answer 2

20. 29130 divided by 5 results in 5832 which is a perfect cube. 18*18*18 = 5832.

21. Area of square = 2304
      S square          =2304
       
                   square will transpose to R.H.S.
               S             = square root of 2304
                S            =48
                  
                 So plants can be arranged in 48 rows and 48 columns
