a carpenter has a wooden stick that is 84 centimeters long.then she cuts of 25% from the end of the stick.then she cuts the remaining into 6 equal pieces.what is the length of each piece?

76

length left over after 25% is cut off
= .75(84)
length of each of the 6 pieces
= .75(84)/6 = 10.5 cm
Are you not concerned about the loss due to all those cuts? 
Using a laser beam of infinitesimal width :)

How did Bentley get 76

= 63
