Ordan has 168 inches of string. He cuts the string into 6 equal pieces. He cuts another 8 inches from each piece.

Each piece is 20 inches long.

Step-by-step explanation:

The length pieces of the ribbon can be obtained by dividing the total length of ribbon by total number of pieces

Given

String length = 168 inches

Number of pieces = 6

So the length of each piece will be:

$Length\ of\ each\ piece = \frac{Length\ of\ string}{Number\ of\ pieces}\\= \frac{168}{6}\\= 28\ inches$

Cutting 8 inches from each piece means that the length will be reduced 8 inches

$Length\ after\ cutting\ 8\ inches = \ length\ of\ each\ piece - 8\\= 28-8\\=20\ inches$

Hence,

Each piece is 20 inches long.
