Question

I need help on this please

Answer 1

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.
