Volume per time

The length of the cube-shaped tank edge is 4 m. A pump has a capacity of 200 l per minute. How long does fill take for a pump to fill a cube-shaped tank up to 75% of its height?

Correct answer:

t =  240 min

Step-by-step explanation:

Q=200 l m3=200:1000  m3=0.2 m3 q=75%=10075=43=0.75 a=4 m  V1=a3=43=64 m3 V2=q V1=0.75 64=48 m3  t=V2/Q=48/0.2=240 min
