The walls of a storage building are built from stone. The stonework costs $5.50 per square foot. The building is 12 feet by 15 feet and 10 feet tall.
How much does it cost to build the storage building walls?
It costs $ to build the storage building.

To determine the cost of building the storage building walls, we need to calculate the total surface area of the walls and then multiply by the cost per square foot.

1. **Calculate the perimeter of the building:**
   \[
   \text{Perimeter} = 2 \times (12\, \text{feet} + 15\, \text{feet}) = 2 \times 27\, \text{feet} = 54\, \text{feet}
   \]

2. **Calculate the total wall area:**
   \[
   \text{Wall Area} = \text{Perimeter} \times \text{Height} = 54\, \text{feet} \times 10\, \text{feet} = 540\, \text{square feet}
   \]

3. **Calculate the cost of the stonework:**
   \[
   \text{Cost} = 540\, \text{square feet} \times \$5.50\, \text{per square foot} = 540 \times 5.50 = \$2970
   \]

Therefore, it costs **$2970** to build the storage building walls.
