Solution -: We are given the volume of a cuboid 2744000 since we are not given the ratios or length , width and height , it means cuboid must be a cube of each side = L
Volume of cube = L^3
2744000 = L^3
L = cube root ( 2744000) = cube root ( 140 * 140 * 140 ) since 140 is in triplet so one 140 will be come out side from cube root
L = 140 m , That would be the length of each side .
