This is my question
A water trough is 8 m long and its cross-section is an isosceles trapezoid which is 80 cm wide at the bottom and 160 cm wide at the top, and the height is 40 cm. The trough is not full. Give an expression for V, the volume of water in the trough in cm^3, when the depth of the water is d cm.
I have tried several things but could not come up with the correct answer, I am on my last try as it is an online learning tool, thanks in advance for any help.
P.S. Not sure if this will help but I have inputted several answers, this being the closest to the answer as far as I think, (800*d^2)+(1600*d^2), not sure if that is any help, but thanks again.
