Jawaban:
panjang DB
[tex]DB = \sqrt{ {BC}^{2} + {CD}^{2} } [/tex]
[tex]DB = \sqrt{ {16}^{2} + {36}^{2} } [/tex]
[tex]DB = \sqrt{256 + 1296} [/tex]
[tex]DB = \sqrt{1552} \: \: cm[/tex]
maka, panjang diagonal ruang DF
[tex]DF = \sqrt{ {DB}^{2} + {BF}^{2} } [/tex]
[tex]DF = \sqrt{( { \sqrt{1552} )}^{2} + {12}^{2} } [/tex]
[tex]DF = \sqrt{1552 + 144} [/tex]
[tex]DF = \sqrt{1696} [/tex]
[tex]DF = 41,182 \: \: cm[/tex]
jadi, panjang diagonal ruang DF adalah 41,182 cm
