So basically you are to use the formula:
L x W x H
Plug the values in:
12 x 1/4 x 4/5
Now we know if we multiply 12 by 1/4 we would 3 since 12 divided by 4 is 3:
3 x 4/5
Multiply the 3 and 4 and get 12/5.
Ok, so to get one of the answers check which one SIMPLIFIES to 12/5, which in this case is 48/20 since that can be simplified by 4.
So the answer is 48/20
