V = area of base * height
Since 1m was cut from each corner, the base is just 1m wide now. Likewise, since the cut was 1m deep, the height is now 1m.
So, the volume = width * height * length
2 = 1 * 1 * length
what, oh, what could be the length?
2? NO! That's the length of the box. The tin sheet has to be 4m long, so the 1m corners can be cut out.
Draw a picture showing width = 3 and
Draw the corner cutouts.
Label the length of each edge
If the total length of the sheet is X,
Then, (X - 2)(1)(1) = 2 making X = 4 meters.
