Cube of 1285

Professor Greenline Explaining Math Concepts

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 1285.

Cube of 1285 for Canadian Students

Cube of 1285

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 1285 can be written as 1285³, which is the exponential form.

 

Or it can also be written in arithmetic form as, 1285 × 1285 × 1285.

How to Calculate the Value of Cube of 1285

In order 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 individuals to cube the numbers faster and easier without feeling confused or stuck while evaluating the answers.

By Multiplication Method

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. 1285³ = 1285 × 1285 × 1285

 

Step 2: You get 2,120,078,625 as the answer.

 

Hence, the cube of 1285 is 2,120,078,625.

Professor Greenline from BrightChamps

Using a Formula (a³)

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 1285 into two parts. Let a = 1200 and b = 85, so a + b = 1285.

 

Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³

 

Step 3: Calculate each term: a³ = 1200³ 3a²b = 3 × 1200² × 85 3ab² = 3 × 1200 × 85² b³ = 85³

 

Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³ (1200 + 85)³ = 1200³ + 3 × 1200² × 85 + 3 × 1200 × 85² + 85³ 1285³ = 1,728,000,000 + 367,200,000 + 260,100,000 + 614,125 1285³ = 2,120,078,625

 

Step 5: Hence, the cube of 1285 is 2,120,078,625.

Professor Greenline from BrightChamps

Using a Calculator

To find the cube of 1285 using a calculator, input the number 1285 and use the cube function (if available) or multiply 1285 × 1285 × 1285.

 

This operation calculates the value of 1285³, resulting in 2,120,078,625. It’s a quick way to determine the cube without manual computation.

 

Step 1: Ensure the calculator is functioning properly.

 

Step 2: Press 1, 2, 8, and 5.

 

Step 3: If the calculator has a cube function, press it to calculate 1285³.

 

Step 4: If there is no cube function on the calculator, simply multiply 1285 three times manually.

 

Step 5: The calculator will display 2,120,078,625.

Problem 1

What is the cube and cube root of 1285?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The cube of 1285 is 2,120,078,625 and the cube root of 1285 is approximately 10.807.

Explanation

First, let’s find the cube of 1285. 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 1285³ = 2,120,078,625 Next, we must find the cube root of 1285.

 

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 ∛1285 ≈ 10.807

 

Hence, the cube of 1285 is 2,120,078,625 and the cube root of 1285 is approximately 10.807.

Problem 4

If a cube with a side length of 1285 cm is compared to a cube with a side length of 85 cm, how much larger is the volume of the larger cube?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The volume of the cube with a side length of 1285 cm is 2,120,078,625 cm³.

Explanation

To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object).

 

Cubing 1285 means multiplying 1285 by itself three times: 1285 × 1285 = 1,651,225, and then 1,651,225 × 1285 = 2,120,078,625.

 

The unit of volume is cubic centimeters (cm³) because we are calculating the space inside the cube. Therefore, the volume of the cube is 2,120,078,625 cm³.
