Answer:
second box
Explanation:
a box has a rectangular prism shape
We know that the formula to calculate the volume of a rectangular prism is width by height by length.
w = width
h = height
l = length
w * h * l = v³
we replace the values we know
box1
3ft * 4 1/2ft * 10 1/4ft =
3ft * 4.5ft * 10.25ft = 138.375ft³
box2
5ft * 12 3/4ft * 11 1/2ft =
5ft * 12.75ft * 11.5ft = 733.125ft³
so we can see the second box has a higher volume so it will have more cereal inside
