# Glass

At the glass shop we have to cut 8 sheets of glass. Each was shaped a square with sides of 18 cm. We paid 44 CZK. How much is a 1 m2 of glass?

Correct result:

x =  169.75 Kc

#### Solution:

$a=18 \ cm \rightarrow m=18 / 100 \ m=0.18 \ m \ \\ \ \\ S_{1}=a^2=0.18^2=\dfrac{ 81 }{ 2500 }=0.0324 \ \text{m}^2 \ \\ x=44/(8 \cdot \ S_{1})=44/(8 \cdot \ 0.0324)=\dfrac{ 13750 }{ 81 }=169.75 \ \text{Kc}$
