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 the cube of 308.
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 308 can be written as 308³, which is the exponential form. Or it can also be written in arithmetic form as, 308 × 308 × 308.
To determine whether a number is a cube number or not, we can use three methods: the multiplication method, a factor formula (a³), or by using a calculator. These methods will help in cubing numbers faster and easier without confusion.
The multiplication method is a process in mathematics used to find the product of numbers by combining them through repeated multiplication. It is a fundamental operation that forms the basis for more complex mathematical concepts.
Step 1: Write down the cube of the given number. 308³ = 308 × 308 × 308
Step 2: You get 29,181,152 as the answer. Hence, the cube of 308 is 29,181,152.
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 308 into two parts, as 300 and 8. Let a = 300 and b = 8, so a + b = 308
Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³
Step 3: Calculate each term
a³ = 300³
3a²b = 3 × 300² × 8
3ab² = 3 × 300 × 8²
b³ = 8³
Step 4: Add all the terms together:
(a + b)³ = a³ + 3a²b + 3ab² + b³
(300 + 8)³ = 300³ + 3 × 300² × 8 + 3 × 300 × 8² + 8³
308³ = 27,000,000 + 2,160,000 + 57,600 + 512
308³ = 29,181,152
Step 5: Hence, the cube of 308 is 29,181,152.
To find the cube of 308 using a calculator, input the number 308 and use the cube function (if available) or multiply 308 × 308 × 308. This operation calculates the value of 308³, resulting in 29,181,152. It’s a quick way to determine the cube without manual computation.
Step 1: Ensure the calculator is functioning properly.
Step 2: Press 3 followed by 0 and then 8
Step 3: If the calculator has a cube function, press it to calculate 308³.
Step 4: If there is no cube function on the calculator, simply multiply 308 three times manually.
Step 5: The calculator will display 29,181,152.
There are some typical errors that might occur during the process of cubing a number. Let us take a look at five of the major mistakes:
What is the cube and cube root of 308?
The cube of 308 is 29,181,152 and the cube root of 308 is approximately 6.679.
First, let’s find the cube of 308. 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 308³ = 29,181,152
Next, we must find the cube root of 308 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 ∛308 = 6.679
Hence the cube of 308 is 29,181,152 and the cube root of 308 is approximately 6.679.
If the side length of the cube is 308 cm, what is the volume?
The volume is 29,181,152 cm³.
Use the volume formula for a cube V = Side³.
Substitute 308 for the side length: V = 308³ = 29,181,152 cm³.
How much larger is 308³ than 300³?
308³ – 300³ = 2,181,152.
First find the cube of 308³, that is 29,181,152
Next, find the cube of 300³, which is 27,000,000
Now, find the difference between them using the subtraction method.
29,181,152 – 27,000,000 = 2,181,152
Therefore, 308³ is 2,181,152 larger than 300³.
If a cube with a side length of 308 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 308 cm is 29,181,152 cm³.
To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object).
Cubing 308 means multiplying 308 by itself three times: 308 × 308 = 94,864, and then 94,864 × 308 = 29,181,152.
The unit of volume is cubic centimeters (cm³), because we are calculating the space inside the cube.
Therefore, the volume of the cube is 29,181,152 cm³.
Estimate the cube of 307.9 using the cube of 308.
The cube of 307.9 is approximately 29,181,152.
First, identify the cube of 308, The cube of 308 is 308³ = 29,181,152.
Since 307.9 is only a tiny bit less than 308, the cube of 307.9 will be almost the same as the cube of 308.
The cube of 307.9 is approximately 29,181,152 because the difference between 307.9 and 308 is very small.
So, we can approximate the value as 29,181,152.
