Question

How many 8 cm cubes can be obtained from a cube whose edge is 16 cm long?

Answer 1

The possible no. of such cubes is 8.

Solution :-

v(cube)=a³

v(bigger cube) n•v(smaller cube) ; n=no. of cubes

i.e. (16)³/(8)³=n

n=4096/512

Hence

n=8

Answer 2

$volume \: of \: cube = side \times side \times side \\ no \: of \: cubes = \frac{volume \: of \: cube \: with \: edge \: 16cm }{volume \: of \: cube \: with \: edge \: 8m} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{16 \times 16 \times 16}{8 \times 8 \times 8} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 2 \times 2 \times 2 = 8$
