Question

The ratio between the length of the edges of two cubes are in the ratio 4:5. Find the ratio between their total surface Area and Volume.

Answer 1

Answer:

Let the edges of a cube 1 and cube 2 be x and y respectively then x:y=3:2

(i)T.S.A of cube1:T.S.A of cube2=6y26x2=y2x2=2232=9:4

(ii)Volume of cube1:Volume of cube2=y3x3=2333=27:8
