panjang diagonal ruang hb = ? panjang diagonal persegi panjang ( alas ) = √ 12^2 + 9 ^2 = √ 144 + 81 = √ 225 = 15 panjang diagonal ruang hb = √ diagonal alas kuadrat + tinggi kuadrat = √ 15 + 8 = √ 225 + 64 = √ 289 = 17

Panjang balok = sisi yang paling panjang = 12 cm AB=GH=12 diagonal ruang HB² = CG² + GH² + BC² = 8² + 12² + 9² = 64 + 144 + 81 = 289 HB = √289 = 17 jadi diagonal ruang = 17 cm
panjang diagonal ruang hb = ?
panjang diagonal persegi panjang ( alas ) = √ 12^2 + 9 ^2
= √ 144 + 81
= √ 225
= 15
panjang diagonal ruang hb = √ diagonal alas kuadrat + tinggi kuadrat
= √ 15 + 8
= √ 225 + 64
= √ 289
= 17
AB=GH=12
diagonal ruang
HB² = CG² + GH² + BC²
= 8² + 12² + 9²
= 64 + 144 + 81
= 289
HB = √289
= 17
jadi diagonal ruang = 17 cm
