Jika volume kubus abcd efgh sama dengan 16√2 maka DF adalah
Penjelasan dengan langkah-langkah:
Volume = 16√2 cm³
d³/(3√3) = 16 √2
d³ = 16√2 . 3√3
d³ = 48√6
d³ = 2⁴ . 3 . √2 . √3
d³ = (2^3/2)³ . (3^1/2)³
d = 2^3/2 . 3^1/2
d = DF = 2√2 . √3
DF = 2√6 cm
n.b : d = diagonal ruang
Kubus
V = r³ = 16√2
r = ³√(16√2)
r = (2^4 . 2^1/2)^1/3
r = 2^(9/2 × 1/3)
r = 2^3/2
r = 2√2
DF = diagonal ruang
DF = r√3
DF = 2√2 . √3
DF = 2√6 satuan
