Question

The volume of two cubes are 729 : 1331. Find the ratio of their edges . What is the ratio of their surface area

Answer 1

let V1 be the volume of first cube , V2 be the volume of second cube , X1 be the length of each side of cube 1 , x2 be the length of each side of cube 2 ,S1 be the surface area of cube1, S2 be the surface area of cube 2

volume of cube =x^3

V1/V2=X1^3/X2^3
X1^3/X2^3=729/1331
X1/X2=9/11 is the ratio of sides of cubes

surface of cube=6X^2

S1/S2=6X1^2/6X2^2
S1/S2=9^2/11^2
S1/S2=81/121 is the ratio of surface areas of cubes
