Question

how many cubes each of surface area 24 cm square can be made out of cube of h = 1 metre​

Answer 1

$surface \: area = 6s {}^{2}$

$6s { }^{2} = 24 \\ s {}^{2} = 24 \div 6 = 4 \\ s = 2$

$volumeofsmall \: cube = 2 {}^{3} \\ = 8cu \: cm$

$volume \: of \: big \: cube = \\ 100 \times 100 \times 100 \\ = 1000000cu \: cm$

$no. \: of \: cubes \: = 1000000 \div 8 \\ = 125000$
