The side of a square is 12 cm. Into how many squares with a side of 3 cm can this square be divided?

Area of a square formula:

S = a², where a is the side of the square.

Let’s calculate the area of the big square:

12² = 12 * 12 = 144 cm² – the area of a large square.

Let’s calculate the area of a small square:

3² = 3 * 3 = 9 cm² – the area of a small square.

Let’s calculate how many small squares a large square can be divided into:

144: 9 = 16 squares – you can divide a big square into that many small squares.

Answer: 16 squares.
