Question

ratio of surface area of 2 cubes=4:9 find the ratio of Thier volumes​

Answer 1

Answer:Let first cube has side a units

other has side b units

total surface area = 6a²

so, S1/ S2 = 4/9

⇒(6a²)/(6b²) = 4/9

⇒a²/b² =(2²/3²)

⇒a/b= 2/3

now, volume of cube = a³

ratio of volume,

V1/V2 = (a/b)³

          = (2/3)³

          = (8/27)

ratio of volume = 8:27
