• C. $56$

Answer 1

$\bullet$ To calculate $2\times 5$ using box method, we can draw a box with $2$ rows and $5$ columns as shown below:

In the above box, the number of cells $=5+5=10$ (as each of the two rows has five columns).

$\therefore$ $2\times 5=$ Number of cells in a box with $2$ rows and $5$ columns= $10$.

$\bullet$ To calculate $3\times 7$ using box method, we can draw a box with $3$ rows and $7$ columns as shown below:

In the above box, the number of cells $=7+7+7=21$ (as each of the three rows has seven columns).

$\therefore$ $3\times 7=$ Number of cells in a box with $3$ rows and $7$ columns= $21$.

$\bullet$ To calculate $8\times 6$ using box method, we can draw a box with $8$ rows and $6$ columns as shown below:

In the above box, the number of cells $=6+6+6+6+6+6+6+6=48$ (as each of the eight rows has six columns).

$\therefore$ $8\times 6=$ Number of cells in a box with $8$ rows and $6$ columns= $48$.
