A trough is 12 feet long and 3 feet across the top. Its end are isolates triangles with altitudes of 3 feet. If water is being pumped into the trough at 2 cubic feet per min, how fast is the water level rising when the water is 1 foot deep?

Yes, actually. But tell me, is the trough like this:dw:1352120844035:dw?

the only thing that makes sense is dw:1352123776310:dw

The ratio of base to altitude of the triangular base is 3/3 = 1 when the water is at height h, the base (width of the water) is also h dw:1352123882327:dw the area as a function of h is 1/2 h^2 volume is 12 * 1/2 *h^2

\[ v= 6 h^2\] \[\frac{dv}{dt}= 12 h \frac{dh}{dt} \] plug in for h and dh/dt to find dv/dt
