Answer 1

Answer:

the side of the new cube would be 6cm

Step-by-step explanation:

volume of a cube = a3

volume of cube1 = (3)3=27

volume of cube2 =(4)3 = 64

volume of cube3 =(5)3 = 125

sum of volumes of all three cubes = 27+64+125

                                                          = 216

volume of new cube = 216

hence side of new cube is 6 cm

( as 216 is 6 cube)
