Jika volume suatu kubus 1728 cm(pangkat 3).hitunglah brapa : a.)diagonal sisi dan b.)diagonal ruang

akhuna V = s x s x s
$s = \sqrt[3]{V}$
$s = \sqrt[3]{1728}$
$s = 12$

Diagonal sisi = s√2 = 12√2

Diagonal ruang = s√3 = 12√3

nurjannahTenri maksud dri jwaban diagonal sisi sma diagonal ruangnya gimana yah ??

akhuna Itu pakai rumus phytagoras. Tapi hasinya memang segitu

nurjannahTenri ohh mksih kak.!tpii aku msih pnya soal yg susah nih bleh nggak minta bantuannya ?

akhuna Silakan :)

MariaRubino V.Kubus = s³
1728 cm³ = s³
s = ∛1728 cm
s = 12 cm

Diagonal sisi => s√2 => 12√2
Diagonal ruang => s√3 = 12√3
