Pool

The swimming pool is 10 m wide and 8 m long and 153 cm deep. How many hectoliters of water is in it, if the water is 30 cm below its upper edge?

Correct result:

V =  984 hl

Solution:

a=10 m b=8 m c1=153−30=123 cm  c=c1→ m=c1/100  m=123/100  m=1.23 m V1=a⋅ b⋅ c=10⋅ 8⋅ 1.23=4925=98.4 m3 V=V1→ hl=V1⋅ 10  hl=98.4⋅ 10  hl=984 hl

IT'S 9 CM NOT 10 CM. SO IT SHOULD BE 4004.
