Answer 1

Answer  The length of the pool is =35 feet. 
        The depth of the pool is = 10 feet.
       Billy's height of the half of the width of pool 
Given  ,  (1/2)x =4.5    (x= width) 
             x= 4.5*2
           x= 9 feet    
so, width = 9 feet 
then we have,  l= 35 feet
               h= 10 feet
               W= 9  feet.  

Now volume will be = l*h*w
                   = 35*10*9
                   =3150 cubic feet
