Question 734653: A water trough is constructed by bending a
4- by 6-foot rectangular sheet of metal down the middle and
attaching triangular ends (see the figure). If the volume of
the trough is 9 cubic feet, find the width correct to two decimal
places. Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! bend in the middle . you will get an isosceles triangle .
The height of triangle will be
=
Area of triangle = (1/2) * base * height
A= sqrt(3)/2 * base
Length = 6 feet
Volume of tank = 6*sqrt(3)/2 * base
9=sqrt(3)/2 * base
Base = width of tank = 6sqrt(3)
