**In this post, we will discuss approximation questions that are on finding cube roots of imperfect cubes IBPS PO, IBPS Clerk, SBI PO, SBI Clerk, SSC CGL, SSC CHSL and other competitive exams.**

Finding cubes roots of imperfect cubes in IBPS PO, IBPS Clerk, SBI PO, SBI Clerk, SSC CGL, SSC CHSL and other competitive exams, is such a tough process. Numbers which do not have a perfect cube, it becomes challenging to find their approximate cube root.In our previous post – Approximation I – Approximation Questions on finding Square Root of Imperfect Squares, we have solved approximation questions that are based on finding the square root of imperfect squares. In this post, we will solve find solutions to the approximation questions that are asked on finding cubes of imperfect cubes.

**Example 4: Approximation questions on finding cube root of imperfect cube**

**Question:**What is the approximate cube of

**√**80000?

**Solution:**

**Step 1:**

**√**80000

**Step 2:**

**√**80000 lies between 40 and 50. We can mark any number that lies between 40 and 50 in the option and most probably a number which is close to 50. But there is a method through which we can find the cube root.

**√**80000 is 42.5.

**Question:**What is the approximate cube of

**√**250000?

**Solution:**

**Step 1:**

**√**250000

**Step 2:**

**√**216000 lies between 60 and 70. We can mark any number that lies between 60 and 70 in the option and most probably a number which is close to 70. But there is a method through which we can find the cube root.

**√**216000 is 62.5.

**Find the cube root of the following approximate questions and drop in your answers in the comment section.**

**Question:**.∛474548.98 = ?

**2) 68 3) 72 4) 76 5) 80**

**Question:**∛1519.985 = ?

for cubes you mention it has ^3 writing 403 for 4 0 cube is confusing
