Question

3 cubes whose sides are 6 cm , 8 cm and 10 cm . they are melted to form a big cube . The​

Answer 1

Volume of the new cube of edge x cm(say)=x^3

which is same as 6^3 +8^3+10^3

=(216+512+1000)cm^3

=1728cm^3

=(12)^3 cm^3

x=12cm

Answer 2

Answer:

Volume of new cube = Volume of 3 cubes.

Volume of 1st cube of side 6cm = a^3 = 216cm^3.

Volume of 2nd Cube of side 8cm = a^3 = 512cm^3.

Volume of 3rd cube of side 10cm = a^3 = 1000cm^3.

Therefore, Sum of three volumes of three cubes = Volume of a big cube

1000cm^3 + 512cm^3 + 216cm^3 = Volume of a big cube

1728 cm^3 = Volume of a big cube.

I hope you understand.

Thanks for asking.
