The number of pieces made from rod is 49
<h3><u>Solution:</u></h3>
Given that A metal rod will be cut into pieces that are each 1/56 meters long
The rod is 7/8 meters long.
<em><u>To find: number of peices made from rod</u></em>
The number of peices made from rod can be calculated by dividing the total length of rod by length of each piece

Here total length of rod =
meters
length of each piece to be made =
meters
Substituting the values in above formula, we get


So the number of pieces made from rod is 49
