Question

If the volumes of two cubes are in ratio 64:1 the ratio in their edges is:

Answer 1

hey!

volume of cube=a^3

ratio of their sides=?

volume of cube( 1)=V1

volume cube( 2)=V2

side of cube(1) = a1

side of cube (2) = a2

V1/V2=64/1 (given)

a1^3/a2^3=64/1

a1/a2=4*4*4/1*1*1

a1/a2=4/1

a1/a2=4:1

hence, sides /edges ratio is 4:1
