Box a has a length of 10 1/4 inch width of 3 inches and a height of 4 1/2 inches box B has a length of 11 1/2 inches width of 5 inches and a height of 12 3/4 inches which box of cereal has more cereal

second box

Step-by-step 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
