Pool

How many hl of water is in a cuboid pool (a = 25m, b = 8m) if the area of the wetted walls is 279.2 m2?

Correct result:

V =  2400 hl

Solution:

a=25 m b=8 m S=279.2 m2  S1=a b=25 8=200 m2 S=S1+2(a+b) c c=SS12 (a+b)=279.22002 (25+8)=65=1.2 m  V1=a b c=25 8 1.2=240 m3  V=V1 hl=V1 10  hl=240 10  hl=2400 hl
