Answer 2

Answer:

the volume the single cube made by smelting all the cubes =volume of cube 1+volume of cube 2+ volume of cube 3

volume of cube one= (a)^3

side of cube one =3

(a)^3 = (3)^3 =27

similarly volume of 2 =64

volume of 3 =125

volume of cube 1+volume of cube 2+ volume of cube 3=

27+64+125 = 216

volume of the cube = 216 cm^3

therefore the side of the cube =6cm
