Question

If the length of the cuboid is doubled and breadth is halved what will be the change in its volume

Answer 1

Answer:

There Will be no Change

Step-by-step explanation:

Let the length of cuboid = l

Let the breadth of cuboid = b

Let the height of the cuboid = h

So it's volume = (l)(b)(h)

= lbs

ATQ,

Let New lenght of cuboid = 2l

Let New breadth of cuboid = 1b/2

And

Let height of cuboid = h

So it's volume = (2l)(1b/2)(h)

= lbs

So if the lenght of cuboid is doubled and the breadth is halved then also there will be no chance in its volume....

Answer 2

$\huge\tt{\underline{\underline{Solution:-}}}$

L = 2l

B = $\sf\frac{1}{3}$ × b

H = 2h

Volume of cuboid= l × b× h

2l × $\sf\frac{1}{3}$b × 2h

$\sf\frac{4}{3}$×l×b×h

➟ $\sf\frac{4}{3}$× original volume.
