A filler is feeding a trough at a rate of 1 cubic meter / second. The troughs dimensions are 12m long with ends shaped like an isosceles triangles which measure 2m vertically and 4m wide. How quickly is the height of the feed in the in the trough increasing after 5 minutes?
A grease trough in the shape of an isosceles trapezoidal prism measures 16m long, 3 m across the bottom, 7m across the top and 4m in height. If the trough is filled at a rate of 4 cubic meters / minute, at what rate is the grease increasing when the depth is 2 meters?
If anyone can answer one or both of those I would greatly appreciate it! Thank you!
