When a number is multiplied by itself thrice, the resultant number is called the cube of a number. Cubing is used while comparing sizes of objects or things with cubic measurements. In this topic, we shall learn about cubes of 345.
A cube number is a value obtained by raising a number to the power of 3, or by multiplying the number by itself three times. When you cube a positive number, the result is always positive. When you cube a negative number, the result is always negative. This is because a negative number multiplied by itself three times results in a negative number. The cube of 345 can be written as 345ยณ, which is the exponential form. Or it can also be written in arithmetic form as, 345 ร 345 ร 345.
In order to check whether a number is a cube number or not, we can use the following three methods, such as the multiplication method, a factor formula (aยณ), or by using a calculator. These three methods will help kids to cube the numbers faster and easier without feeling confused or stuck while evaluating the answers. By Multiplication Method Using a Formula Using a Calculator
The multiplication method is a process in mathematics used to find the product of two numbers or quantities by combining them through repeated addition. It is a fundamental operation that forms the basis for more complex mathematical concepts. Step 1: Write down the cube of the given number. 345ยณ = 345 ร 345 ร 345 Step 2: You get 41,020,125 as the answer. Hence, the cube of 345 is 41,020,125.


The formula (a + b)ยณ is a binomial formula for finding the cube of a number. The formula is expanded as aยณ + 3aยฒb + 3abยฒ + bยณ. Step 1: Split the number 345 into two parts, as 300 and 45. Let a = 300 and b = 45, so a + b = 345 Step 2: Now, apply the formula (a + b)ยณ = aยณ + 3aยฒb + 3abยฒ + bยณ Step 3: Calculate each term aยณ = 300ยณ 3aยฒb = 3 ร 300ยฒ ร 45 3abยฒ = 3 ร 300 ร 45ยฒ bยณ = 45ยณ Step 4: Add all the terms together: (a + b)ยณ = aยณ + 3aยฒb + 3abยฒ + bยณ (300 + 45)ยณ = 300ยณ + 3 ร 300ยฒ ร 45 + 3 ร 300 ร 45ยฒ + 45ยณ 345ยณ = 27,000,000 + 12,150,000 + 1,822,500 + 91,125 345ยณ = 41,020,125 Step 5: Hence, the cube of 345 is 41,020,125.
To find the cube of 345 using a calculator, input the number 345 and use the cube function (if available) or multiply 345 ร 345 ร 345. This operation calculates the value of 345ยณ, resulting in 41,020,125. Itโs a quick way to determine the cube without manual computation. Step 1: Ensure the calculator is functioning properly. Step 2: Press 3 followed by 4 and 5 Step 3: If the calculator has a cube function, press it to calculate 345ยณ. Step 4: If there is no cube function on the calculator, simply multiply 345 three times manually. Step 5: The calculator will display 41,020,125.
The cube of any even number is always even, while the cube of any odd number is always odd. The product of two or more perfect cube numbers is always a perfect cube. A perfect cube can always be expressed as the product of three identical groups of equal prime factors.
There are some typical errors that kids might make during the process of cubing a number. Let us take a look at five of the major mistakes that kids might make:
What is the cube and cube root of 345?
The cube of 345 is 41,020,125, and the cube root of 345 is approximately 7.000.
First, letโs find the cube of 345. We know that the cube of a number, such that xยณ = y Where x is the given number, and y is the cubed value of that number So, we get 345ยณ = 41,020,125 Next, we must find the cube root of 345 We know that the cube root of a number โxโ, such that โx = y Where โxโ is the given number, and y is the cube root value of the number So, we get โ345 โ 7.000 Hence the cube of 345 is 41,020,125, and the cube root of 345 is approximately 7.000.
If the side length of the cube is 345 cm, what is the volume?
The volume is 41,020,125 cmยณ.
Use the volume formula for a cube V = Sideยณ. Substitute 345 for the side length: V = 345ยณ = 41,020,125 cmยณ.
How much larger is 345ยณ than 300ยณ?
345ยณ โ 300ยณ = 14,020,125.
First find the cube of 345, which is 41,020,125 Next, find the cube of 300, which is 27,000,000 Now, find the difference between them using the subtraction method. 41,020,125 โ 27,000,000 = 14,020,125 Therefore, 345ยณ is 14,020,125 larger than 300ยณ.
If a cube with a side length of 345 cm is compared to a cube with a side length of 45 cm, how much larger is the volume of the larger cube?
The volume of the cube with a side length of 345 cm is 41,020,125 cmยณ.
To find its volume, we multiply the side length by itself three times (since itโs a 3-dimensional object). Cubing 345 means multiplying 345 by itself three times: 345 ร 345 = 119,025, and then 119,025 ร 345 = 41,020,125. The unit of volume is cubic centimeters (cmยณ), because we are calculating the space inside the cube. Therefore, the volume of the cube is 41,020,125 cmยณ.
Estimate the cube of 344.9 using the cube of 345.
The cube of 344.9 is approximately 41,020,125.
First, identify the cube of 345, The cube of 345 is 345ยณ = 41,020,125. Since 344.9 is only a tiny bit less than 345, the cube of 344.9 will be almost the same as the cube of 345. The cube of 344.9 is approximately 41,020,125 because the difference between 344.9 and 345 is very small. So, we can approximate the value as 41,020,125.
Binomial Formula: It is an algebraic expression used to expand the powers of a number, written as (a + b)โฟ, where โnโ is a positive integer raised to the base. The formula is used to find the square and cube of a number. Cube of a Number: Multiplying a number by itself three times is called the cube of a number. Exponential Form: It is a way of expressing numbers using a base and an exponent (or power), where the exponent value indicates how many times the base is multiplied by itself. For example, 3ยณ represents 3 ร 3 ร 3 equals 27. Volume of a Cube: The amount of space occupied by a cube, calculated using the formula V = sideยณ. Perfect Cube: A number that can be expressed as the cube of an integer.
