$\huge\red\bigstar$QUESTION :-

A solid cube of by edge 10 cm is melted and cast into a cuboid whose base measures 20cm by 10 cm. find the height of the cuboid.

$\huge\pink\bigstar$ANSWER:-

$\red\implies$ Volume of Cube = Side³

                            $\red\implies$ (10 cm)³

                         $\red\implies$   1000 cm³    ...(1.)

$\red\implies$ This is melted and cast into the Cuboid. The Volume of Cuboid so made will be equal to the Volume of the Cube.

$\red\implies$ Let the height of the cuboid be h cm.

Then,

$\red\implies$ Volume of Cuboid = l × b × h

                               = 20 × 10 × h

                               = 200h      ...(2.)

$\red\implies$ Equating (1.) and (2.),

$\red\implies$ We have 200h = 1000

                    $\red\implies$ h = 1000/200

                    $\red\implies$   h = 5

$\huge\red\bigstar$.°. the height of the cuboid is 5 cm.
