# Water depth

How many square meters of the inside of the pool wet the water if the pool is 25 meters long and 10 meters wide and the water depth is 1.2 meters everywhere.

Result

S =  334 m2

#### Solution:

$a = 25 \ m \ \\ b = 10 \ m \ \\ h = 1.2 \ m \ \\ \ \\ S_{ 1 } = a \cdot \ b = 25 \cdot \ 10 = 250 \ m^2 \ \\ \ \\ S_{ 2 } = 2 \cdot \ (a+b) \cdot \ h = 2 \cdot \ (25+10) \cdot \ 1.2 = 84 \ m^2 \ \\ \ \\ S = S_{ 1 }+S_{ 2 } = 250+84 = 334 = 334 \ m^2$
