Penjelasan dengan langkah-langkah:
Diketahui
p= 24
l= 7
t= 8
D= √689
Luas db=√(l²+t²)×p
= √ (7²+8²)×p
= √(49+64)×24
= 7+8 ×24
= 15×24 = 360
Volume balok = p×l× t
= 24×7×8
= 1344
Semoga membantu dan bermanfaat
Diket : p = 24 cm, l = 7 cm, t = 8 cm, diagonal ruang = √689 cm
Dit : L bidang diagonal = ? dan V = ?
Jwb : bidang diagonal = √7²+8² = √113 cm, Luas bidang diagonal = p x bidang diagonal = 24x√113 = 24√113 cm²
V = pxlxt = 24x7x8 = 1344 cm³
