The correct option is
B 124×3 can be shown in the form of a box containing
3 rows and
4 columns as:
4×3 would be equal to the total number of balls contained in all the cells of the box.
∴ Total number of balls in the box=
4+4+4=12 (as each of
3 rows contains
4 columns).
Therefore,
4×3=12, which we have calculated easily using
Box Method––––––––––––––––.
