Answer:
43cm
Step-by-step explanation:
Given
Length of Log = 291cm
First Piece = 67cm
Second Piece = 181cm
Required
Determine the length of the third piece
Given that the log was cut into three;
<em>this implies that;</em>
Length of Log = First Piece + Second Piece + Third Piece
Substitute values for first piece, second piece and length of log;


Subtract both sides by 248



<em>Hence, the length of the third piece is 43cm</em>
