Dimensions of cuboid=100*80*64 cm
Vol. of cuboid =100*80*64 cm cube
Vol. Of cuboid =vol. Of cube
100*80*64=(side)3
Side of cube=8
CSA of cube=6(side)2
=6(8*8)=384 m cube

First multiply length, breadth and heigh which will give you 0.512m^3.Then find one side which will be0.8m because if cube 0.8m you will get volume of cuboid. Then multiply 0.8 with 6 and 0.8 which is formula of surface area of cube. Answer will be 3.64m^2
