Let's solve the given question step by step.
1. Identify the given parameter values:
- Depth = 2
- Height = 4
2. Determine the formula for Width:
- Width = Height 2
- Width = 4 2
- Width = 8
3. Check each option with the given parameter values to see which formula correctly accounts for Depth=2.
Option A: Depth = Width / 2
- Substitute the value of Width:
- Depth = 8 / 2
- Depth = 4
- This does not match the given Depth of 2.
Option B: Depth = (Height + Width) / 6
- Substitute the values of Height and Width:
- Depth = (4 + 8) / 6
- Depth = 12 / 6
- Depth = 2
- This matches the given Depth of 2.
Option C: Depth = Height + Width / 6
- This notation could potentially mean either `Height + (Width/6)` or `(Height + Width)/6` but the parentheses are required.
- If it means `Height + (Width / 6)`:
- Depth = 4 + (8 / 6)
- Depth = 4 + 1.3333
- Depth ≈ 5.3333
- This does not match the given Depth of 2.
- If it means `(Height + Width) / 6`, it is already checked in Option B.
Option D: Depth = (Width + Height) / 4
- Substitute the values of Height and Width:
- Depth = (8 + 4) / 4
- Depth = 12 / 4
- Depth = 3
- This does not match the given Depth of 2.
So, the correct formula is Option B: Depth = (Height + Width) / 6.
