5) The Louvre museum in Paris features an inverted square pyramid with a height of 10 m. The side of the square is 13 m. Supervillains decide to fill the pyramid with water, and do so at a rate of 10 m 3 per second. How quickly is the water level rising when it reaches the top? 8)Water is leaking from a trough at the rate of 0.8 L/s.The trough has a trapezoidal cross section, where the width at the bottom is 55 cm, at the top is 85cm, and the height is 25 cm. The length of the trough is 3 m.Find the rate at which the height is changing when the depth of water is 11 cm
