Answer:

28

Step-by-step explanation:

So in order to get this answer you want to use the combination formula which is $\frac{n!}{(n-r)!r!}$

Now you want to use the numbers given to you in the problem which is ₈C₂ and plug those into the equation

LenKa [72]

Answer:

44,55,000 cubic meters of treasure could fit the pyramid.

Step-by-step explanation:

We are given the following in the question:

Base measure = 450 meters

Height = 66 meters

The volume of the pyramid is given by:

$V = \dfrac{AH}{3}$

where A is the ares of the base and H is the height of the pyramid.

Putting values, we get,

$V = \dfrac{1}{3}\times (450\times 450) \times 66\\\\V = 4455000\text{ cubic meters}$

Thus, 4455000 cubic meters of treasure could fit the pyramid.
