Answer 1

Answer:

if this helps u then mark me as brainliest and follow me....

Step-by-step explanation:

As we know that,

Volume of cube =a

3

Here, a is the edge of cube

Volume of small cube of edge 6cm=6

3

=216cm

3

Volume of small cube of edge 8cm=8

3

=512cm

3

Volume of small cube of edge 10cm=10

3

=1000cm

3

Here,

Volume of new cube = Sum of colume of all cubes

Therefore,

Volume of new cube =1000+216+512=1728cm
