I have this question posed to me for homework.
A parabolic prism is being filled with water. The top of the prism is 30cm wide and is 20cm deep. What is the depth of the water when the prism is half full.
I have found the area of the face to be 110 cm2 , by finding the equation of the parabola and then the integral between -15 and +15.
Given that the volume of a prism is Ah, to be half full would be found with (A/2)h.
This is where I get stuck.
Help?
