As the cereal box would be a rectangular prism, you would need to multiply the length, the width, and the height together to find the volume of the box. By multiplying (2*5.33*10.75) I got the answer (114.595 or 114.6). So 114.6 would be the answer for A, with the (2*5.33*10.75) being the work you are showing. In order to see how much volume a single serving takes up, you would take the 114.6 and divide it by 8, so you would have (114.6/8). When dividing 114.6 by 8, you would get the answer (14.325 or 14.3). The answer to B would be 14.3, with the (114.6/8) being the work that you are showing.
