Answer 1

9 cubes can be made from cube edges 2.7

Solution:

The volume of cube is given as:

$Volume\ of\ cube = a^3$

Where "a" is the edge

Find volume of cube of edge 0.9 cubic units

$Volume\ of\ cube = 0.9^3\\\\Volume\ of\ cube = 0.81\ cubic\ units$

Find volume of cube of edge 2.7

$Volume\ of\ cube = 2.7^3\\\\Volume\ of\ cube = 7.29\ cubic\ units$

Find the number of cubes that can be made

$Number\ of\ cubes = \frac{7.29}{0.81}\\\\Number\ of\ cubes = 9$

Thus 9 cubes can be made
