Answer:
Step-by-step explanation:
Given that :
Length of board = 16 feet
Converting length of Board to inches:
1 foot = 12 inches
Total initial length in inches = (16 * 12) = 192 inches
To cut in 11 equal pieces : blade will have to be used 10 times
Since the Blade changes the length of each. Piece by - 0.125 inches
The total change or reduction in inch:
-0. 125 inches * 10 pieces = - 1.250 inches
Hence the total change in length :
Initial length - total reduction ;
192 inches - 1.250 inches
192 - 1.250 = 190.750
Therefore, size of each shelf will be:
190.750 / 11
= 17.34
