1. Denotar las dimensiones del estanque rectangular:
- Largo: 3x
- Ancho: x
- Profundidad: 2x

2. Utilizar la fórmula del volumen para expresar el volumen del estanque en función de x:
V = (3x) \cdot x \cdot (2x)

3. Igualar al volumen dado de 1296 m³ y resolver para x:

3x \cdot x \cdot 2x = 1296

6x^3 = 1296

4. Dividir ambos lados por 6:

x^3 = \frac{1296}{6}

x^3 = 216

5. Tomar la raíz cúbica de ambos lados:

x = \sqrt[3]{216}

x = 6

6. Multiplicar x por 2 para encontrar la profundidad:

2x = 2 \cdot 6

7. Respuesta:

2x = 12\, \text{m}
