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:

$$\begin{gathered} a=10\text{ m } \\ b=5\text{ m } \\ c=50\text{ cm}\to \text{ m}=50\mathrm{/}100\text{ m}=0.5\text{ m } \\ S=a\cdot b+2\cdot (a+b)\cdot c=10\cdot 5+2\cdot (10+5)\cdot 0.5=65{\text{m}}^2 \end{gathered}$$

$$\begin{gathered} V_1=a\cdot b\cdot c=10\cdot 5\cdot 0.5=25{\text{m}}^3 \\ V=V_1\to \text{ hl}=V_1\cdot 10\text{ hl}=25\cdot 10\text{ hl}=250\text{ hl} \end{gathered}$$
