Question

The reason I can't solve this (I think, LOL) is because I don't know the formula for a trapezoidal prism. Can you guys help me out?

A horizontal trough is 16 meters long and its ends are isosceles trapezoids with an altitude of 4 meters, a lower base of 4 meters and an upper base of 6 meters. Water is being poured into the trough at the rate of 10 m^3/min. How fast is the water level rising when the water is 2 m deep?

Answer 1

volume is
\[\frac{1}{2}bhl\]

Answer 2

oh wait. hold on

Answer 3

i feel like a 2 year old

Answer 4
