A trough has a parabolic cross section
y
=
a
x
2
, where
a
is a constant. The height is
H
meters and the length is
L
meters. The trough is filled with water. For this problem, approximate the weight density of water to be
ρ
g
=
10
4
Newtons per cubic meter.
square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get your answer!
