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?

Result

S =  65 m2
V =  250 hl

Solution:

a=10 m b=5 m c=50 cm=50/100 m=0.5 m  S=a⋅ b+2⋅ (a+b)⋅ c=10⋅ 5+2⋅ (10+5)⋅ 0.5=65=65 m2a = 10 \ m \ \\ b = 5 \ m \ \\ c = 50 \ cm = 50 / 100 \ m = 0.5 \ m \ \\ \ \\ S = a \cdot \ b + 2 \cdot \ (a+b) \cdot \ c = 10 \cdot \ 5 + 2 \cdot \ (10+5) \cdot \ 0.5 = 65 = 65 \ m^2
V1=a⋅ b⋅ c=10⋅ 5⋅ 0.5=25 m3 V=V1→hl=V1⋅ 10 hl=250 hl=250  hl V_{ 1 } = a \cdot \ b \cdot \ c = 10 \cdot \ 5 \cdot \ 0.5 = 25 \ m^3 \ \\ V = V_{ 1 } \rightarrow hl = V_{ 1 } \cdot \ 10 \ hl = 250 \ hl = 250 \ \text { hl }
