Expert Answer:
Total volume of 3 cubes = (33 + 43 + 53 ) cm3
= (27 + 64 + 125)cm3
= 216 cm3
Now volume of new cube = 216 cm3
So edge of new cube = cube root of 216 cm3
= 6 cm
Total volume of 3 cubes = (33 + 43 + 53 ) cm3
= (27 + 64 + 125)cm3
= 216 cm3
Now volume of new cube = 216 cm3
So edge of new cube = cube root of 216 cm3
= 6 cm
