According to the statement of the question, the width of the larger box equals 2 times the width of the box shown, then the width of the larger box equals 10 cm (2×5), the rest of the dimensions of the box remain the same.
We have to calculate how much cereal can fit in the larger box, that is the internal volume of the box (the space inside the box where we can fit the cereal), the volume of a box is given by the following formula:
[tex]V=w\times l\times h[/tex]
In this case, w equals 10 cm, l equals 30 cm and h equals 40 cm, then we get:
[tex]V=10\times30\times40=12000[/tex]
Then, we can fit 12000 cubic centimeters of cereal inside the larger box
