Answer:

He can fit 2 more DVD's on the shelf.

And he'll have about 12 mm of extra space left.

Step-by-step explanation:

40×1.4 = 56cm  This is the length of space the 40 DVD's will take up.

60-56 = 4cm  This is the amount of space left.

4/1.4 = 2.857   the number of DVD's that will fit.

Of course, the decimal represents a partial DVD which is worthless.

Just to be sure, 2×1.4 = 2.8cm OK. But  3×1.4=  4.2cm which is 2mm too much
