Question

the measures of a cuboid are 15 cm into 12 cm into 6 CM having melted this cuboid small cubes of side 3 cm are casted find the number of cube requested

Answer 1

Volume of cuboid=lbh
=15*12*6
=1080cm^3

volume of each cube=s^3
=27cm^3

total cubes casted= 1080/27
=40

40 cubes are casted

Answer 2

Volume of cuboid = l × b × h
= 15cm × 12cm × 6cm
= 1080cm^3

It says Upon melting Small Cubes of Side 3cm are formed.

Volume of Cube = l^3
= 3^3
= 27cm^3

Volume Of Cuboid/Volume Of Cube = Number Of Cubes

1080/27

= 40 cubes needed

Hope it helps you!
