Question

The volume of a cuboid is 36000 cm. If its breadth and height are 30 cm
and 20 cm respectively, find its length.
(A) 45 cm (B) 60 cm (C) 40 cm (D) 50 cm​

Answer 1

Answer:

volume of a cuboid is 36000 cm.

breadth and height are 30 cm

and 20 cm respectively

volume =lbh

36000=l(30)(20)

36000=l(600)

l=36000/600

l=60cm

Answer 2

Given :-

It's given that the volume of a cuboid is 36,000cm³. Also, it's breadth and height are 30cm and 20cm respectively.

To find :-

Now, we have to find the length of the cuboid.

Solution :-

Here, it is said that 36,000cm³ is the volume of a cuboid and also, it's breadth and height are 30cm and 20cm.

We know that : Volume of a cuboid = lbh, where :

• l = Length of the cuboid
• b = Breadth of the cuboid
• h = Height of the cuboid

Now, we'll substitute the values and find the length of the cuboid :

• l(30cm)(20cm) = 36,000cm³
• l(600cm²) = 36,000cm³
• l = 36,000cm³/600cm²
• l = 60cm

__________________________

Therefore, the length of the cuboid is 60cm [Option B] whose volume, breadth and height are 36,000cm³, 30cm and 20cm respectively.
