Homework Statement
The cross section of a canal can be modeled by a parabola.
The canal is 80 m wide at ground level and 20 m deep at its lowest point.
The canal is 0.8 km long.
Find the volume of water in the canal when it is full to ground level.
Homework Equations
Will add them once I find out what they actually are.
The Attempt at a Solution
I've deduced so far that the derivative of the parabola (if that's even relevant to the question) will cross the x-axis axis at the vertex/lowest point of the canal. This point is at 40 metres across.
Problem is, I don't know what to do with this information. I'm assuming I'm supposed to construct the equation of the parabola somehow, but I don't know how to do that.
Any help would be much appreciated.
