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 888.
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 by itself three times results in a negative number.
The cube of 888 can be written as 888³, which is the exponential form. Or it can also be written in arithmetic form as 888 × 888 × 888.
In order to check whether a number is a cube number or not, we can use the following three methods, such as multiplication method, a factor formula (a³), 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.
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.
888³ = 888 × 888 × 888
Step 2: You get 700,227,072 as the answer.
Hence, the cube of 888 is 700,227,072.
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 888 into two parts, as 800 and 88.
Let a = 800 and b = 88, so a + b = 888
Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³
Step 3: Calculate each term
a³ = 800³
3a²b = 3 × 800² × 88
3ab² = 3 × 800 × 88²
b³ = 88³
Step 4: Add all the terms together:
(a + b)³ = a³ + 3a²b + 3ab² + b³
(800 + 88)³ = 800³ + 3 × 800² × 88 + 3 × 800 × 88² + 88³
888³ = 512,000,000 + 168,960,000 + 24,768,000 + 681,472
888³ = 700,227,072
Step 5: Hence, the cube of 888 is 700,227,072.
To find the cube of 888 using a calculator, input the number 888 and use the cube function (if available) or multiply 888 × 888 × 888. This operation calculates the value of 888³, resulting in 700,227,072. It’s a quick way to determine the cube without manual computation.
Step 1: Ensure the calculator is functioning properly.
Step 2: Press 8 followed by 8 and 8.
Step 3: If the calculator has a cube function, press it to calculate 888³.
Step 4: If there is no cube function on the calculator, simply multiply 888 three times manually.
Step 5: The calculator will display 700,227,072.
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 888?
The cube of 888 is 700,227,072 and the cube root of 888 is approximately 9.634.
First, let’s find the cube of 888.
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 888³ = 700,227,072.
Next, we must find the cube root of 888.
We know that the cube root of a number ‘x’, such that ³√x = y, where ‘x’ is the given number, and y is the cube root value of the number.
So, we get ³√888 ≈ 9.634.
Hence, the cube of 888 is 700,227,072 and the cube root of 888 is approximately 9.634.
If the side length of the cube is 888 cm, what is the volume?
The volume is 700,227,072 cm³.
Use the volume formula for a cube V = Side³.
Substitute 888 for the side length: V = 888³ = 700,227,072 cm³.
How much larger is 888³ than 400³?
888³ – 400³ = 699,827,072.
First find the cube of 888³, that is 700,227,072.
Next, find the cube of 400³, which is 64,000,000.
Now, find the difference between them using the subtraction method.
700,227,072 – 64,000,000 = 636,227,072.
Therefore, the 888³ is 636,227,072 larger than 400³.
If a cube with a side length of 888 cm is compared to a cube with a side length of 100 cm, how much larger is the volume of the larger cube?
The volume of the cube with a side length of 888 cm is 700,227,072 cm³, and it is larger by 699,627,072 cm³ than the cube with a side length of 100 cm.
To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object).
Cubing 888 means multiplying 888 by itself three times: 888 × 888 = 788,544, and then 788,544 × 888 = 700,227,072.
The unit of volume is cubic centimeters (cm³), because we are calculating the space inside the cube.
The volume of the cube with a side length of 100 cm is 1,000,000 cm³.
Therefore, the larger cube is 700,227,072 - 1,000,000 = 699,227,072 cm³ larger.
Estimate the cube of 887 using the cube of 888.
The cube of 887 is approximately 700,227,072.
First, identify the cube of 888, The cube of 888 is 888³ = 700,227,072.
Since 887 is only a tiny bit less than 888, the cube of 887 will be almost the same as the cube of 888.
The cube of 887 is approximately 700,227,072 because the difference between 887 and 888 is very small.
So, we can approximate the value as 700,227,072.
