Question

a book is 30cm long and 4 cm thick if the volume of the book is 2400 cm cuboid find the width of the book class 5th​

Answer 1

L=30cm

H=4cm

V=2400

or, l×b×h=2400

or, 30×b×4=2400

or, b=2400÷120

:width(b)=20cm

Answer 2

Answer:

20cm

Step-by-step explanation:

Given,

Length = 30cm, Height or thickness = 4cm, Volume of cuboid = 2400 cm³

Now,

Volume of Cuboid = 2400

L x B x H = 2400

30 x B x 4 = 2400

120 x B = 2400

B = 2400/120

B = 20cm

Therefore, the breadth or width of the book is 20cm
