First One     Volume of the base = x * x * 4x = 4x^3

                   + Volume of pyramid top  x*x*x/3 = x^3/3

         Answer A

 

Second One 

   cylinder volume   pi r^2 h = 452.16

                               pi (6^2) h = 452.16    results in   h~~4.0 cm  (not necessary for solution)

 

Cone volume = pi r^2 h/3

                      = pi (6^2)h/3 = 452.16       results in h = ~~ 12 cm for the equivalent volume cone with same size lid(6cm)

            Answe   B
