Answer:
900,000 books.
Step-by-step explanation:
The volume of the container = 24 * 9 * 8
= 1728 m^3
The volume of each book = 20*16*6 = 1920 cm^3
There are 100*100*100 = 1,000,000 cm^3 in 1 m^3.
So the number of books the container can hold
= (1728 * 1000000) / 1920
= 900,000.
Answer:
Radius x radius x 3.14 / 2 = area of semicircle
5 x 5 x 3.14 = 78.5
don't divide because there is two semicircle
22-10=12
12 x 10 = 120
120 + 78.5 = 198.5 cm squared
