suatu balok berukuran panjang 16 cm,Lebar 12cm,dan Tinggi 15cm.Hitunglah:A)Panjang diagonal sisi B)Panjang diagonal Ruang

jwab

p= 16 cm
l  = 12 cm
t = 15 cm

diagonal  sisi (pl)= √(p²+l²) = √16²+12² = √400 = 20
diagonal sisi (pt)  = √(p²+t²) = √16²+15² = √481
diagonal sisi (lt) = √l²+t² = √12²+ 15²= √369 = 3√41

diagonal ruang =√p²+l²+t² = √16²+12²+15²= √625=  25
