How many square meters of tiles do we need to tile the walls and floor of the pool, 15 meters long, six meters wide, and two meters deep?

Correct answer:

S =  174 m²

Step-by-step explanation:

$$\begin{gathered} a=15\text{m} \\ b=6\text{m} \\ c=2\text{m} \\ S=a\cdot b+2\cdot (a+b)\cdot c=15\cdot 6+2\cdot (15+6)\cdot 2=174{\text{m}}^2 \end{gathered}$$
