Question

The length of a book is 20cm, width is 15cm and height is 1cm. Find out the volume of 15 books?

plz answer quickly.​

Answer 1

Given:-

• Length ,l = 20 cm

• Breadth ,b = 15 cm

• Height ,h = 1 cm

To Find:-

• Volume of 15 Books

Solution:-

As we know that

Volume of Cuboid = l×b×h

Substitute the value we get

→ Volume = 20×15 × 1

→ Volume = 300 cm³

Therefore volume of 1 book is 300 cm³.

Now Volume of 15 books = 15 × 300

= 4500cm³

Therefore , the required answer is 4500cm³.

Additional Information!!

• Area of Square = Side × Side

• Area of Rectangle = Length × Breadth

• Area of Rhombus = 1/2 × d1 × d2

here

d1 is the 1st diagonal of Rhombus

d2 is the second diagonal of Rhombus

• Area of Parallelogram = Base × Height

• Perimeter of Square = 4 × Side

• Perimeter of Rectangle = 2 (Length + Breadth)

• Area of Triangle = 1/2 × base × height

• Perimeter of triangle = Sum if their sides

• Circumference of Circle = 2πr

where,

π = 22/7

r is the radius of Circle

Answer 2

Answer:

= 4500 sq. cm

Explanation:

lenght = 20cm

width = 15cm

height = 1

volume of 1 book  = lbh

=20x15x1

=300 sq.cm
