Question

A rectangular solid measuring its in 8cm × 2 cm is melted the cost in the form of a cube the solid of the cube fromis all solutions

Answer 1

Volume of CUBOID = $9*8*2 = 144cm^{3}$

Edge of Cube = $2cm$

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

Numbers of cubes formed by melting the CUBOID = Volume of CUBOID/Volume of each cube $= \frac{144}{8} = 18$

Hence ,

$18$ cube's can by formed by melting the CUBOID
