1680
Step-by-step explanation:
Since there are 4 places (frames) to put up each poster, we think individually:
In the first place they can place ANY OF THE 8 POSTERS
In 2nd place, they can place ANY OF THE REMAINING 7 POSTERS
In 3rd place, they can place ANY OF THE REMAINING 6 posters
and
in last place, they can place ANY OF THE REMAINING 5 posters
The number of ways is the multiplication of them all, so:
8 * 7 * 6 * 5 ways = 1680 ways
Answer:
Step-by-step explanation:
We have been given that a square pyramid has a base with a side length of 7.5 feet and lateral faces with heights of 16 feet. We are asked to find the surface area of the square pyramid.
We will use surface area of square pyramid to solve our given problem as:
, where,
a = Length of each side of base,
h = Height of lateral face.
Upon substituting our given values in above formula, we will get:
Therefore, the surface area of the given square prism would be 592.50 square feet.
