Ответ:
El ancho de la superficie = 444,44 my el largo = 200 m
La superficie de la superficie de la presa = 88888,89 m²
Step-by-step explanation:
Los parámetros dados son;
La altura del agua en la presa = 225 m
El volumen de agua en la presa, d = 20 millones de m³
La longitud de la base = 200 m
Sea el ancho de la presa = x
El volumen viene dado por la relación;
200 × 225 × x = 20 millones de m³
x = 20.000.000 / (200 × 225) = 444,44 m
Por tanto, las dimensiones de la superficie son ancho = 444,44 my largo = 200 m
El área de superficie de la superficie de la presa = 444.44 × 200 = 88888.89 m².
