When a number is multiplied by itself thrice, the resultant number is called the cube of a number. Cubing is used when comparing sizes of objects or things with cubic measurements. In this topic, we shall learn about the cube of 1018.
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 1018 can be written as 1018³, which is the exponential form. Or it can also be written in arithmetic form as, 1018 × 1018 × 1018.
To check whether a number is a cube number or not, we can use the following three methods: multiplication method, a factor formula (a³), or by using a calculator. These three methods will help kids cube the numbers faster and easier without feeling confused or stuck while evaluating the answers.
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. 1018³ = 1018 × 1018 × 1018
Step 2: You get 1,055,888,232 as the answer. Hence, the cube of 1018 is 1,055,888,232.
The formula (a + b)³ is a binomial formula for finding the cube of a number. The formula is expanded as a³ + 3a²b + 3ab² + b³.
Step 1: Split the number 1018 into two parts, as 1000 and 18. Let a = 1000 and b = 18, so a + b = 1018
Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³
Step 3: Calculate each term
a³ = 1000³
3a²b = 3 × 1000² × 18
3ab² = 3 × 1000 × 18²
b³ = 18³
Step 4: Add all the terms together:
(a + b)³ = a³ + 3a²b + 3ab² + b³
(1000 + 18)³ = 1000³ + 3 × 1000² × 18 + 3 × 1000 × 18² + 18³
1018³ = 1,000,000,000 + 54,000,000 + 972,000 + 5,832
1018³ = 1,055,888,232
Step 5: Hence, the cube of 1018 is 1,055,888,232.
To find the cube of 1018 using a calculator, input the number 1018 and use the cube function (if available) or multiply 1018 × 1018 × 1018. This operation calculates the value of 1018³, resulting in 1,055,888,232. It’s a quick way to determine the cube without manual computation.
Step 1: Ensure the calculator is functioning properly.
Step 2: Press 1, 0, 1, and 8
Step 3: If the calculator has a cube function, press it to calculate 1018³.
Step 4: If there is no cube function on the calculator, simply multiply 1018 three times manually.
Step 5: The calculator will display 1,055,888,232.
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 1018?
The cube of 1018 is 1,055,888,232 and the cube root of 1018 is approximately 10.069.
First, let’s find the cube of 1018.
We know that the cube of a number, such that x³ = y Where x is the given number, and y is the cubed value of that number
So, we get 1018³ = 1,055,888,232
Next, we must find the cube root of 1018
We know that the cube root of a number ‘x’, such that ∛x = y Where ‘x’ is the given number, and y is the cube root value of the number
So, we get ∛1018 ≈ 10.069
Hence the cube of 1018 is 1,055,888,232 and the cube root of 1018 is approximately 10.069.
If the side length of the cube is 1018 cm, what is the volume?
The volume is 1,055,888,232 cm³.
Use the volume formula for a cube V = Side³.
Substitute 1018 for the side length: V = 1018³ = 1,055,888,232 cm³.
How much larger is 1018³ than 1000³?
1018³ – 1000³ = 55,888,232.
First, find the cube of 1018³, that is 1,055,888,232
Next, find the cube of 1000³, which is 1,000,000,000
Now, find the difference between them using the subtraction method. 1,055,888,232 – 1,000,000,000 = 55,888,232
Therefore, 1018³ is 55,888,232 larger than 1000³.
If a cube with a side length of 1018 cm is compared to a cube with a side length of 500 cm, how much larger is the volume of the larger cube?
The volume of the cube with a side length of 1018 cm is 1,055,888,232 cm³.
To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object).
Cubing 1018 means multiplying 1018 by itself three times: 1018 × 1018 = 1,036,324, and then 1,036,324 × 1018 = 1,055,888,232.
The unit of volume is cubic centimeters (cm³), because we are calculating the space inside the cube.
Therefore, the volume of the cube is 1,055,888,232 cm³.
Estimate the cube 1017.5 using the cube 1018.
The cube of 1017.5 is approximately 1,055,888,232.
First, identify the cube of 1018, The cube of 1018 is 1018³ = 1,055,888,232.
Since 1017.5 is only a tiny bit less than 1018, the cube of 1017.5 will be almost the same as the cube of 1018.
The cube of 1017.5 is approximately 1,055,888,232 because the difference between 1017.5 and 1018 is very small.
So, we can approximate the value as 1,055,888,232.
