If a books 15cm long 20cm wide and 1cm height what is the volume of 50 such books?
Answers
Volume of a cuboid = (length × breadth × height) cubic units.
= (l × b × h) cubic units.
(Since area = ℓ × b)
Volume of a cuboid = area of one surface × height cubic units
Let us look at the given cuboid.
The length of the cuboid = 5 cm
The breadth of the cuboid = 3 cm
The height of cuboid (thickness) = 2 cm
The number of 1 cm cubes in the given cuboid = 30 cubes = 5 × 3 × 2
We find that volume of the given cuboid with length 5 cm, breadth 3 cm and height 2 cm is 30 cu cm.
Answer: 15,000cm³
Step-by-step explanation: First let’s find the volume of 1 book, to find the volume of something we multiply the length by the width by the depth (you can say height but depth is the proper terminology,) so 15 x 20 x 1, well, 15 x 20 = 300, and 300 x 1 = 300, so the volume of 1 book is 300cm³ (the little 3 means cubed, squared is used for a flat object, but as the book is 3 dimensional, we used cubed.)
So now we must mutliply that by 50 to get the volume of 50 books, 300cm³ x 50 = 15,000cm³.
So there is your answer, 15,000cm³.
Hope this helps.
