albert needs 30 meters of wood to build a large wooden frame> He bought three different lengths of wood measuring 12.5, 11.43 and 7.244 metere. After he builds the frame, how many meters will albert have left?

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.
