To find out how much the carpenter needs to cut off from the piece of wood, we need to subtract the length of the shelf from the total length of the wood piece.
First, let's convert the lengths into the same unit. Since the length of the shelf is given in centimeters, let's convert the length of the wood piece and the length of the saw into centimeters as well.
1 meter is equal to 100 centimeters, so the length of the wood piece is:
1m = 1 * 100cm = 100cm
Similarly, the length of the saw is 33cm.
Now, we can calculate the amount that needs to be cut off by subtracting the length of the shelf and the length of the saw from the length of the wood piece:
Wood Piece Length: 100cm + 26cm = 126cm
Amount to be cut off: 126cm - 86cm - 33cm = 7cm
Therefore, the carpenter needs to cut off 7 centimeters from the piece of wood to make it fit.
