A book contains 360 pages which measure 20cm. By14cm. Every page has a blank margin 2.5cm. deep long each short side and 2cm. Deep each long side Find the total area available for painting
Answers
Length of printing area = 20 - 2 x 2
= 20 - 4
= 16
Breadth of printing area = 14 - 2 x 2.5
= 14 - 5
= 9
So, printing area on each page = 16 x 9 = 144
The book has 360 pages.
Total printing area = 144 x 360
= 51840 cm²
= 5.184 m².
Answer:
54000 cm²
Step-by-step explanation:
Each page measures 20 cm X 14 cm
Counting out the margins on all four side, the dimensions of the page will be
(14 - 2 - 2) = 10 cm
and
(20 - 2.5 - 2.5) = 15 cm
So, area available to paint on one page = 10 X 15
= 150 cm²
Since there are 360 pages in the book
Total area for painting = 150 X 360
= 54000 cm²
