To find the area of a square, square the length of one side. For example, if the side length is 4 inches, the area is 4² = 16 square inches (in²).
To find the area of a square with a side length of s inches, you need to use the formula for the area of a square, which is Area = s², where 's' represents the length of a side of the square.
Let's consider an example. If each side of the square is 4 inches, to find the area, you would square the side length. In this case, that would be 4² = 16. Therefore, the area of this square is 16 square inches.
The symbol for square inches is in², reflecting that we are measuring area or a two-dimensional space. This concept can be extended to any unit of measurement; if we were using feet instead of inches, for example, we would express the area in square feet (ft²).

To find out how many grains of sand are in 6300kg, you need to first convert the weight from kg to g and then divide the total weight by the weight of one grain of sand. In this case, the answer is 9 × 10¹³ grains of sand.
To answer your question, we first need to convert the weight from kilograms (kg) to grams (g) since the weight of a grain of sand is given in grams. There are 1,000,000 grams (g) in a kilogram (kg), so 6300kg is equal to 6,300,000,000g (or 6.3 × 10⁹ g in standard form).
Next, we divide the total weight in grams by the weight of a single grain of sand to find the number of grains in the given weight. So, if one grain of sand weighs 0.0007g, we divide the total weight (6.3 × 10⁹ g) by the weight of a single grain of sand to get
9 × 10¹³ grains of sand. This means there are 9 × 10¹³ grains of sand in 6300kg.
