Question

what is the total number of meridiens at an interval of 5 degree?

Answer 1

The earth is divided into 360 meridians or longitude. So, after every 5 degrees we will be able to draw

360/5 meridians
= 72 meridians

Answer 2

The whole earth is divided into '360' meridians over the years.  

EXPLANATION:

So at an interval of 5 degrees the total 360 degrees will be divided and would result in 360 /5 = 72 each .

And meridian can be defined as a imaginary line that joins the 'south pole' and the 'north pole' across the earth . Therefore, the 'total number of meridians' at an interval of '5 degree' is found to be '360'
