(25)^3= 25*25*25
25*25*25
=625*25
=15625
First Step: Digit in ten’s place is 1, so we write the cube of 1. And also as the ratio between 1 and 2 is 1:2, the next digits will be double the previous one. So, the first row is 1, 2, 4, 8.
Step II: In the above row our 2nd and 3rd digits (from right) are 4 and 2 respectively. So, we write down 8 and 4 below 4 and 2 respectively. Then add up the two rows.

Step-by-step explanation:
25 cube 3 is simple.
25X25X25. we multiply the same no 3 times because it is a cube.
so you imagine a cube.
it has length, breadth and height.
in this length=25,
breadth=25 and
height=25. to fine volume we will multiply all.
like that multiply this.
you can think that it is hard to multiply this.
you can substitute 25=5X5.
so we will get
5X5X5X5X5X5.
now it is simple.
when you multiply you will get
15,625.
try this. it will be easy.
i hope you think it easy.
if you think it is easy,mark this as the brainliest.
please...
