Respuesta :

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.
