A number we multiply by itself three times to get the original number is its cube root. It has various uses in real life, such as finding the volume of cube-shaped objects and designing structures. We will now find the cube root of 0.003375 and explain the methods used.
We have learned the definition of the cube root. Now, let’s learn how it is represented using a symbol and exponent. The symbol we use to express the cube root is the radical sign (∛), and the exponent we use is ⅓. In exponential form, ∛0.003375 is written as 0.003375^(1/3). The cube root is just the opposite operation of finding the cube of a number. For example: Assume ‘y’ as the cube root of 0.003375, then y^3 can be 0.003375. Since the cube root of 0.003375 is not an exact value, we can write it as approximately 0.15.
Finding the cube root of a number is to identify the number that must be multiplied three times resulting in the target number. Now, we will go through the different ways to find the cube root of 0.003375. The common methods we follow to find the cube root are given below: - Prime factorization method - Approximation method - Subtraction method - Halley’s method To find the cube root of a non-perfect number, we often follow Halley’s method. Since 0.003375 is not a perfect cube, we use Halley’s method.
Let's find the cube root of 0.003375 using Halley’s method. The formula is ∛a ≅ x((x^3 + 2a) / (2x^3 + a)) where: a = the number for which the cube root is being calculated x = the nearest perfect cube Substituting, a = 0.003375; x = 0.1 ∛a ≅ 0.1((0.1^3 + 2 × 0.003375) / (2 × 0.1^3 + 0.003375)) ∛0.003375 ≅ 0.1((0.001 + 0.00675) / (0.002 + 0.003375)) ∛0.003375 ≅ 0.15 The cube root of 0.003375 is approximately 0.15.
Finding the cube root of a small decimal number without any errors can be a difficult task for students. This happens for many reasons. Here are a few mistakes the students commonly make and the ways to avoid them:
Imagine you have a small cube-shaped object that has a total volume of 0.003375 cubic meters. Find the length of one side of the cube equal to its cube root.
Side of the cube = ∛0.003375 = 0.15 units
To find the side of the cube, we need to find the cube root of the given volume. Therefore, the side length of the cube is approximately 0.15 units.
A company has 0.003375 cubic meters of a rare material. Calculate the amount of material left after using 0.001 cubic meters.
The amount of material left is 0.002375 cubic meters.
To find the remaining material, we need to subtract the used material from the total amount: 0.003375 - 0.001 = 0.002375 cubic meters.
A container holds 0.003375 cubic meters of liquid. Another container holds 0.002 cubic meters of liquid. What would be the total volume if the liquids are combined?
The total volume of the combined liquids is 0.005375 cubic meters.
Explanation: Let’s add the volume of both containers: 0.003375 + 0.002 = 0.005375 cubic meters.
When the cube root of 0.003375 is multiplied by 2, calculate the resultant value. How will this affect the cube of the new value?
2 × 0.15 = 0.3 The cube of 0.3 = 0.027
When we multiply the cube root of 0.003375 by 2, it results in a significant increase in the volume because the cube increases exponentially.
Find ∛(0.002 + 0.001).
∛(0.002 + 0.001) = ∛0.003 ≈ 0.144
As shown in the question ∛(0.002 + 0.001), we can simplify that by adding them. So, 0.002 + 0.001 = 0.003. Then we use this step: ∛0.003 ≈ 0.144 to get the answer.
Cube root: The number that is multiplied three times by itself to get the given number is the cube root of that number. Perfect cube: A number is a perfect cube when it is the product of multiplying a number three times by itself. A perfect cube always results in a whole number. For example, 2 × 2 × 2 = 8, therefore, 8 is a perfect cube. Exponent: The exponent form of the number denotes the number of times a number can be multiplied by itself. In x^(1/3), ⅓ is the exponent which denotes the cube root of x. Radical sign: The symbol that is used to represent a root is expressed as (∛). Irrational number: Numbers that cannot be put in fractional forms are irrational. For example, the cube root of 0.003375 is irrational because its decimal form goes on continuously without repeating the numbers.
