Question

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?

Answer 1

After Albert builds the frame, 1.174 meters of wood will be left.

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.
