Question

the volume of cuboid is 840 cm cube . If the length and breadth of the cuboid is 21 cm and 8 cm respectively, find its height​

Answer 1

Answer:

height = 5cm

Step-by-step explanation:

volume=840cm³

lenght = 21cm

breadth=8cm

height= 840/(21×8)

= 840/168

= 5 cm

Answer 2

Answer:

➙ The height of the cuboid is 5cm.

Step-by-step explanation:

Given dimensions of the cuboid :

• → Volume = 840cm³
• → length = 21cm.
• → breadth = 8cm.
• → height = ??

Here, volume, length and breadth is given we need to find it's height.

So,

Let's consider the height as "h" cm.

We know that,

➙ Volume of a cuboid = l • b • h

From the given dimensions :

➙ 840 = 21 • 8 • h

➙ 840 = 168 • h

➙ 840/168 = h

➙ 5 = h

or, h = 5cm.

∴The height of the cuboid is 5cm.
