Question

three cubes of metal of edges 6cm, 8cm, and 10cm are melted to form a new cube. find the diagonal of the new cube​

Answer 1

Answer:

Volume of cube=a^3

Volume of first cube=6^3=216cm^3

Volume of second cube=8^3=512cm^3

Volume of third cube=10^3=1000cm^3

Volume of new cube formed=216+512+1000

=1728cm^3

Volume of cube= a^3

1728=a^3

a=3√1728

a=12cm

Diagonal of cube=√3a

=√3×12

=√36cm
