Just do 6.99 divided by 3
(a)$2.33
times your answer in (a) by 10
(b)$23.3
Answer:
Step-by-step explanation:
A) You are painting 5 faces, four sides and the bottom, of the pool because you are not painting the top of the pool.
B) You need 104 square meters to paint the pool.
Assuming the pool is a rectangular prism, use the surface area equation:
SA = wl + 2(hl) + 2(hw)
Note: Do not include times 2 for wl because we are only including the bottom of the pool.
l = 8 meters
w = 6 meters
h = 2 meters
SA = (6)(8) + 2((2)(8)) + 2((2)(6))
SA = 104 square meters
C) The paint with cost $624 total. $104 times 6 square meters equals $624
The correct answer is the option number 1, which is:
a(v)=√(3V/8)
The explanation is shown below:
To solve this problem you must apply the following proccedure:
1. You must use the formula for calculate the volume of a square pyramid, which is:
V=a²h/3
2. Therefore, when you clear a, you obtain:
3V=a²h
3V/h=a²
a=√(3V/h)
3. You have that heigth is 8, then:
a(v)=√(3V/8)
4. So, as you can see, the correct answer is the option mentioned above.
