First, we need to find the volume of the pan. We do this by multiplying the length, width, and height together. This is:

Next, we find the volume of the pieces of bread. We do this the same way.

Finally, we figure out how many times 10 can go into 250. We do this by dividing 250 by 10.
250/10=25, so Arla can cut 25 pieces of bread.
