Question

11.
A pipe is in the shape of a cuboid. Its length is 2m, width 5 cm, and thickness 5 cm. The volume
of the pipe in cubic metres is:
(1) 0.050 m
(2) 0.0050 m
(3) 0.50 m
(4) 0.055 m​

Answer 1

$3)0.5m \: \: \: \: \:$

Answer 2

Answer:

(2) 0.0050 m

Step-by-step explanation:

Let's explain how we got this :

Length = 2 m.

Width = 5 cm.

Converting 5 cm into metre, we get-

(5/100) m. i.e 1/20 m.

Thickness = 1/20 m. ( Same as Width)

As per Statement,

Cracking out formula of volume using length, width and thickness is --

Volume of a cuboid = Length×Width×Thickness.

So, required volume = (2×1/20×1/20)

or, 1/200 m. (After solving out)

Converting the value of volume in decimal fraction (as required in the question) --

(200÷1) or 0.005 m. (Ans.)
