Times Table explainer

The aim of this puzzle: Calculate the total number of boxes by multiplying the rows and columns.

Walkthrough of the solution: The area of a rectangle is calculated by multiplying the height and width. In the same way, you can calculate the total number of boxes arranged in a rectangle by multiplying the number of rows by the number of columns.

The multiplication symbol in JavaScript is the asterisk *. The total variable should store the rows times the columns. Delete the 100, and replace it with rows * columns.

Sample code solution:
(Tap below to reveal)

print(rows + 'x' + columns);
var total = rows * columns;
print(total + ' boxes');
