Question

The volume of a two cube 8: 1 then find the ratio of their edges

Answer 1

We are given ratio of volumes= 8:1

Let sides be a and A

so, a^3/A63 = 1/8

 so, a/A = 1/2

Answer 2

Hi ,

Let a and s are edges of two cubes .

ratio of their volumes = 8 : 1

a³ / s³ = 8 / 1

( a/ s )³ = ( 2/1 ) ³

Therefore ,

a : s = 2 : 1

Required ,

ratio of edges = a : s = 2 : 1

I hope this helps you.
