Answer 1

l*w*h

10*4*5

200 So the answer to part A is it is the correct size since it is at least 180 cubic inches. It is greater than that.

Part B

This is just multiplication. If it was just 1 cubic inch it would be 15 cents. Two cubic inches is 30 cents and so on. We happen to have 200 cubic inches, so 200*.15 is $30
