<u>Given</u>:
The given figure is a square pyramid.
The side length of the base of the pyramid is 6.6 feet.
The height of the pyramid is 12.672 feet.
We need to determine the volume of the pyramid.
<u>Area of the base:</u>
The area of the base can be determined using the formula,
where a is the side length of the base.
Substituting a = 6.6, we get;
Thus, the area of the base is 43.56 square feet.
<u>Volume of the pyramid:</u>
The volume of the pyramid can be determined using the formula,
where A is the area of the base and h is the height of the pyramid.
Substituting A = 43.56 and h = 12.672, we get;
Thus, the volume of the pyramid is 184 cubic feet.
So from 1150 to 230 lbs of flour remaining...
The percentage decrease was by
percentage decrease = ((b-a)/b)*100
b is the original value
a is the other value
p= ((1150-230)/1150)*100
p = (920 /1150) * 100
p = (0.8) * 100
p = 80
The percentage decrease is 80% from 1150 to 230 lbs of flour.
Hope this helps :)
Answer:
Step-by-step explanation: sorry I don't give answers to you but I not love you why you are a baby
A = 864
w = 2/3l
A = lw
Plug in what we know:
864 = l(2/3l)
Multiply:
864 = 2/3l^2
Divide 2/3 to both sides or multiply by its reciprocal, 3/2:
864 * 3/2 = l^2
2592/2 = l^2
1296 = l^2
Find the square root of both sides:
l = 36
So the length of the basement is 36 feet.
Add 5 to both sides The Addition Property of Equality
