Hey mate!!

Here's your answer

1) the side of the one face of the cube
= 40cm/4
=10cm
then the volume = 10^3
= 1000cm^3
2) the ratio of volume = 1:27
so the ratio of sides = 3√1 : 3√27
= 1:3
the ratio of their surface area = 1×1 : 3×3
= 1:9
3) let the radii be 2x and 3x
let the height be 5y and 3y
ratio of the CSA = rh/RH
= 2x×5y/3x×3y
= 10xy/9xy
= 10/9 = 10:9

Hope it helped you.....Please mark me as brainliest....
