Step 1: Calcular el área del salón
La fórmula para el área de un rectángulo es \( A = l \times w \), donde \( l \) es la longitud y \( w \) es el ancho. Aquí, \( l = 12 \) ft y \( w = 9 \) ft. Entonces, \( A = 12 \times 9 = 108 \) ft².
Step 2: Calcular el costo total del piso
El costo por pie cuadrado es $3.75, y el área es 108 ft². Entonces, el costo total es \( 108 \times 3.75 = 405 \) dólares.
Step 3: Calcular el número de cajas necesarias
Cada caja cubre 18 ft². Entonces, el número de cajas es \( \frac{108}{18} = 6 \).
