How many liters of water are in a pool whose width is 12 m, length 25 m, and depth 280 cm if it is filled 10 cm below the edge?
What is the area of ​​the walls that wet the water (in m2)?

Correct answer:

V =  810000 l
S =  499.8 m2

Step-by-step explanation:

a=12 m b=25 m c=28010=270 cm c1=c m=c:100  m=270:100  m=2.7 m  V1=a b c1=a b 1027=12 25 2.7=810 m3  V=V1 l=V1 1000  l=810 1000  l=810000 l=810000 l
S=a b+2 (a+b) c1=a b+2 (a+b) 1027=12 25+2 (12+25) 2.7=499.8 m2
