Question

Alex wants to fit all of his DVDs onto a shelf that is 60 cm long. Each DVD is 1.4 cm wide. He has 40 DVDs. How many more DVDs can fit on the shelf?

Answer 1

To find out how many more DVDs can fit on the shelf, calculate the total width of the DVDs already on the shelf and subtract it from the length of the shelf. Alex can fit 4 more DVDs on the shelf.

Step-by-step explanation:

To find out how many more DVDs can fit on the shelf, we need to calculate the total width of the DVDs already on the shelf and then subtract it from the length of the shelf.

The width of each DVD is 1.4 cm, and Alex has 40 DVDs. So the total width of the 40 DVDs is 1.4 cm x 40 = 56 cm.

Now, we subtract the total width from the length of the shelf: 60 cm - 56 cm = 4 cm. Therefore, Alex can fit 4 more DVDs on the shelf.
