First, we need to find the volume of the pan. We do this by multiplying the length, width, and height together. This is:
[tex]volume=10*12 \frac{1}{2} *2=250 in^{3} [/tex]
Next, we find the volume of the pieces of bread. We do this the same way.
[tex]volume=2*2 \frac{1}{2}*2=10in^{3} [/tex]
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.
