Question

The dimensions of a piece of iron in the shape of a cuboid are 33*30*42. of the cuboid is melted and cast into cubes of side 3 cm. Find the number of cubes obtained

Answer 1

Answer:

1540

Step-by-step explanation:

dimensions of cuboid = 33×30×42

side of cube = 3cm

So,

Volume of cuboid = 33×30×42 = 41580 and

Volume of cube = a^3 = 3^3 = 27

Now,

No. of cubes obtained

= Volume of cuboid/Volume of cube

= 41580/27

= 1540

Hence, No. of cubes formed = 1540

Answer 2

Answer:

1540

Step-by-step explanation:

dimensions of cuboid = 33×30×42

side of cube = 3cm

So,

Volume of cuboid = 33×30×42 = 41580 and

Volume of cube = a^3 = 3^3 = 27

Now,

No. of cubes obtained

= Volume of cuboid/Volume of cube

= 41580/27

= 1540

Hence, No. of cubes formed = 1540
