Step 2: Multiply the number by itself using the multiplication button (×) That is 618 × 618
Step 3: Press the equal to button to find the answer Here, the square of 618 is 381,924.
Tips and Tricks for the Square of 618
Tips and tricks make it easy for students to understand and learn the square of a number. To master the square of a number, these tips and tricks will help students.
- The square of an even number is always an even number. For example, 6² = 36
- The square of an odd number is always an odd number. For example, 5² = 25
- The last digit of the square of a number is always 0, 1, 4, 5, 6, or 9.
- If the square root of a number is a fraction or a decimal, then the number is not a perfect square. For example, √1.44 = 1.2
- The square root of a perfect square is always a whole number. For example, √144 = 12.
Common Mistakes to Avoid When Calculating the Square of 618
Mistakes are common among kids when doing math, especially when it is finding the square of a number. Let’s learn some common mistakes to master the squaring of a number.
Mistake 1
Calculation errors:
Calculation errors mostly happen when students skip the steps or else by swapping the digits. To avoid it, students should double-check the answer. They can double-check by finding the square root of the solution they found. For example, the square of 25 is 625, and the square root of 625 is ±25.
Solved Examples on Square of 618
Problem 1
Find the length of the square, where the area of the square is 381,924 cm².
The area of a square = a²
So, the area of a square = 381,924 cm²
So, the length = √381,924 = 618.
The length of each side = 618 cm
Explanation
The length of a square is 618 cm. Because the area is 381,924 cm², the length is √381,924 = 618.
Problem 2
Anna wants to install tiles on her square kitchen floor with a length of 618 feet. The cost to install tiles per square foot is 10 dollars. How much will it cost to tile the entire floor?
The length of the floor = 618 feet
The cost to install tiles per square foot = 10 dollars.
To find the total cost to install tiles, we find the area of the floor,
Area of the floor = area of the square = a²
Here a = 618
Therefore, the area of the floor = 618² = 618 × 618 = 381,924.
The cost to tile the floor = 381,924 × 10 = 3,819,240.
The total cost = 3,819,240 dollars
Explanation
To find the cost to tile the floor, we multiply the area of the floor by the cost to install tiles per foot. So, the total cost is 3,819,240 dollars.
Problem 3
Find the area of a circle whose radius is 618 meters.
The area of the circle = 1,199,393.32 m²
Explanation
The area of a circle = πr²
Here, r = 618
Therefore, the area of the circle = π × 618² = 3.14 × 618 × 618 = 1,199,393.32 m².
Problem 4
The area of a square is 381,924 cm². Find the perimeter of the square.
The perimeter of the square is 2,472 cm.
Explanation
The area of the square = a²
Here, the area is 381,924 cm²
The length of the side is √381,924 = 618
Perimeter of the square = 4a
Here, a = 618
Therefore, the perimeter = 4 × 618 = 2,472.
Problem 5
Find the square of 619.
The square of 619 is 383,161.
Explanation
The square of 619 is multiplying 619 by 619. So, the square = 619 × 619 = 383,161
