The pool

The pool is 25 meters long, 10 meters wide, and 1.5 meters deep. How many liters are needed to fill it completely? How much will the new floor and wall paneling cost if one m2 costs 10 euros?

Correct answer:

V =  375000 l
x =  3550 eur

Step-by-step explanation:

a=25 m b=10 m c=1.5 m  V1=a b c=25 10 1.5=375 m3  V=V1 l=V1 1000  l=375 1000  l=375000 l=375000 l
p=10 eur/m2  S=a b+2 (a+b) c=25 10+2 (25+10) 1.5=355 m2  x=p S=10 355=3550 eur
