Question

Find the cube of 0.5

Answer 1

0.125 is the answer exactly

Answer 2

Answer:

0.125

Step-by-step explanation:

To Find:- Cube of 0.5

Solution:-

A decimal number is a number which comprise of a whole number and a fractional part which is written after a decimal point ( . ).

0.5 is a terminating decimal number as it has a single digit after the decimal point.

Here we need to find the cube of the decimal number 0.5.

Now, we will first express the decimal number as the fraction with numerator and denominator.

We can write 0.5 as

0.5 = $\frac{5}{10}$

Now, we will find the cube of the numerator and denominator.

Cube of 5 = 5 ^ 3 = 5 × 5 × 5

                 = 125

Cube of 10 = 10 ^ 3 = 10 × 10 × 10

                  = 1000

Now, putting the fraction back, we get $\frac{125}{1000}$

Converting the fraction into decimal, we get

                           $\frac{125}{1000}$ = 0.125

Therefore, cube of 0.5 is 0.125.
