in this case volume remain equal
volume of 1 cube = a^3
6^3
=216cm^3
volume 2 cube =8^3
512cm^3
volume of 3 cube= 10^3
1000cm^3
after melting to form a single cube their volumes is add
volume of new cube = 216+512 +1000
a^3 = 1728cm^3
a = 12 cm (cube root of 1728 is 12)
volume of 1 cube = a^3
6^3
=216cm^3
volume 2 cube =8^3
512cm^3
volume of 3 cube= 10^3
1000cm^3
after melting to form a single cube their volumes is add
volume of new cube = 216+512 +1000
a^3 = 1728cm^3
a = 12 cm (cube root of 1728 is 12)
