Answer:
After Albert builds the frame, 1.174 meters of wood will be left.
Step-by-step explanation:
Here, the total length of wood required to build wooden frame = 30 meters
The length of the wooden pieces collected are:
First piece = 12.5 m
Second Piece = 11.43 m
and Third Piece = 7.244 m
Now, the total length of wood all pieces combined
= Length of (First + second + third ) Piece
= 12.5 m + 11.43 m + 7.244 m = 31.174 m
So, the combined length of all wooden pieces = 31.174 m
Now, the left over length = Total wood collected - The length required
= 31.174 m = 30 m = 1. 174 m
Hence, after he builds the frame, 1.174 meters wood will be left.
