Answer to Question #23793 in Geometry for upmanyu

Question

water flows in a tank at the rate of 2.5 litres per second. calculate the time it would take to fill the tank with a rectangular base 75 by 100 cm to a height of 64 cm.

Answer 1

The volume of water that fills the tank with a rectangular base 75 by 100 cm to
a height of 64 cm is

V = 75[cm]*100[cm]*64[cm] = 480000[cm³] = 480[L].

Therefore, the time needed to fill the tank to a height of 64 cm is

T = 480[L]/2.5[L/s] = 192[s].
