Volume increase

How many percent will increase in the pool 50 m, width 15m if the level rises from 1m to 150cm?

Correct result:

p =  50 %

Solution:

S=50⋅ 12=600 h1=1 h2=150/100=32=1.5 V1=h1⋅ S=1⋅ 600=600 V2=h2⋅ S=1.5⋅ 600=900 p1=(V2−V1)/V1⋅ 100=(900−600)/600⋅ 100=50 p=(h2−h1)/h1⋅ 100=(1.5−1)/1⋅ 100=50%
