Not that you know how long number 11 actually is, but you would be able to compare number 11 against the Pantheon with number 11 against the Baths of Caracalla, and so on and so forth. If you were interested.
Não se trata de saber o comprimento do número 11, mas de poder comparar  o número 11 com o Panteão o número 11 com as Termas de Caracala, etc. Se estiverem interessados.
