Question Continuation:
if (a) the books can be arranged in any order?
(b) the mathematics books must be together and the novels must be together?
Answer:
(a) 3628800 ways
(b) 17280 ways
Step-by-step explanation:
Given
Solving (a): In any order
This implies that there is no restriction and the novels, mathematics and biology book are just seen as books.
Total number of books is:
The number of arrangement is:
(b):
If the mathematics books are together, there are 4! different arrangements
If the novels are together, there are 5! different arrangements
Now, there are 3 bundles.
- The mathematics books as 1
- The novels as 1
- The biology book
This can be arranged in 3! ways.
Total number of arrangement is:
The side length of the base of the souvenir is 9cm.
A square pyramid -shaped souvenir has a volume of 216 cm^3
and the height is 8 cm.
What is square pyramid ?
A three - dimensional geometric shape having a square base and four triangular faces/sides that meet at a single point (called vertex) is called a square pyramid. It is called a pentahedron, due to its five faces.
Now, Using the formula of Volume of square pyramid
V =
Solving for a
a ==
a = 9cm
Thus, The side length of the base of the souvenir is 9cm.
