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 m=18/100  m=0.18 m  S1=a2=0.182=812500=0.0324 m2 S=8 S1=8 0.0324=162625=0.2592 m2  x=44/S=44/0.2592=1375081=169.75 Kc



We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
