The problem states:

**"Compute in per square foot method: A 10m x 18m board room needs how many watts of light? If using a 30W bulb/lamp, how many lighting fixtures are needed? Draw and illustrate how you will lay this out in the ceiling layout (drawings and sketches do not need to be to scale)."**

Let's break down the solution:

### Step 1: Calculate the Area of the Room
The room dimensions are:
- Length = 10 meters
- Width = 18 meters

So, the area \( A \) is calculated as:
\[
A = \text{Length} \times \text{Width} = 10 \, \text{m} \times 18 \, \text{m} = 180 \, \text{m}^2
\]

### Step 2: Convert Square Meters to Square Feet
1 square meter is approximately 10.764 square feet. So, the area in square feet is:
\[
180 \, \text{m}^2 \times 10.764 \, \text{ft}^2/\text{m}^2 \approx 1937.52 \, \text{ft}^2
\]

### Step 3: Determine the Required Wattage per Square Foot
A typical office or boardroom requires around 1.5 to 2 watts per square foot for adequate lighting. Assuming we use 1.5 watts per square foot:
\[
\text{Total watts required} = 1937.52 \, \text{ft}^2 \times 1.5 \, \text{watts/ft}^2 \approx 2906.28 \, \text{watts}
\]

### Step 4: Determine the Number of 30W Bulbs Needed
Each bulb is 30 watts, so the number of bulbs required is:
\[
\text{Number of bulbs} = \frac{\text{Total watts required}}{\text{Wattage per bulb}} = \frac{2906.28 \, \text{watts}}{30 \, \text{watts/bulb}} \approx 97 \, \text{bulbs}
\]

### Step 5: Layout Plan for the Ceiling
To evenly distribute 97 bulbs across a 10m x 18m boardroom, you can:
- Arrange bulbs in a grid pattern, maintaining uniform spacing.
- For simplicity, divide the length and width evenly and distribute the bulbs based on this pattern.

Here are 5 related questions:
1. What would the total power consumption be if each bulb is left on for 8 hours daily?
2. How would the number of bulbs change if you used LED bulbs with higher efficiency?
3. What is the impact of using a lower wattage per square foot for lighting efficiency?
4. How can you ensure uniform lighting distribution in a room?
5. What role does room color and surface reflectivity play in lighting requirements?

**Tip**: Always consider the color and reflectivity of the room's surfaces when designing lighting layouts, as these factors can significantly affect the overall lighting needs.

Compute in per square foot method: A 10m x 18m board room needs how many watts of light? If using a 30W bulb/lamp, how many lighting fixtures are needed? Draw and illustrate how you will lay this out in the ceiling layout (drawings and sketches do not need to be scaled).
