Question

What is the volume of 50 books such as 20 cm in length, 15 cm in width and 1 cm in height?

Answer 1

Explanation:

dimensions of 1 book = 20 , 15 , 1 cm.

volume of 1 book = l×b×h= 20×15×1 cm³

= 300cm³

volume of 50 books = 300×50

= 15000 cm³

Answer 2

volume = height × length × breadth

volume of 1 book = 20× 15 × 1

= 300cm³ = 3M³

volume of 50 books = 3metre × 50

= 150m³
