Question

A cube of side8cms is cut into smallest cubes of side 2 cm each.Fine d no of cubes​

Answer 1

$\boxed{\boxed{\underline{\huge{\bold{\green{\mathfrak{Answer}}}}}}}$

The volume of the large cube of side 8cm

$= (a) {}^{3} = (8cm) {}^{3} = 512cm {}^{3}$

The volume of the smallest cube of side

2cm

$= (a) {}^{3} = (2cm) {}^{ 3} = 8cm {}^{3}$

The number of cubes of side 2cm which can be cut from the large cube of side 8cm

no. of cubes=vol of large cube/vol of small cube

$= \frac{512cm {}^{3} }{8cm {}^{3} }$

Number of cubes
