Children's pool

Children's pool at the swimming pool is 10m long, 5m wide and 50cm deep. Calculate:

(a) how many m2 of tiles are needed for lining the perimeter walls of the pool?
(b) how many hectoliters of water will fit into the pool?

Correct result:

S =  65 m2
V =  250 hl

Solution:

a=10 m b=5 m c=50 cm m=50/100  m=0.5 m  S=a b+2 (a+b) c=10 5+2 (10+5) 0.5=65 m2
V1=a b c=10 5 0.5=25 m3 V=V1 hl=V1 10  hl=25 10  hl=250 hl
