Answer: So a 1 pound = 0.453592kg
the density of the water is D= 997 kg/[tex]m^{3}[/tex] so we need to use replace the kg with pounds with 2.20462 pounds = 1kg.
then D = 2.20462*997 pounds/[tex]m^{3}[/tex]
and we want to make this equal to one changing the metters for other thing.
we need to replace [tex]x^{3}[/tex] with 2.020462*997 meters qube.
then our new metters variable x = 12.6meters.
now g = 9.8 meters for second square.
in our new lenght variable x.
g = 12.6*9.8 x for second square.
so if y is our new time variable
[tex]y^{2}[/tex] = 12.6*9.8 seconds square. so y = 11.1seconds
so the units of length are x = 12.6 meters and for time y = 11.1 seconds.
