Sebuah balok abcd efgh berukuran P = 12 cm L = 7 cm T = 10 cm Hitunglah: A.panjang diagonal bidang Ac? B.panjang diagonal ruang Ag??

AB = cd = ef = gh = 12 cm
ad = bc = fg = eh = 7 cm
ae = bf = cg = dh = 10 cm

A. panjang AC
= √ab²+bc²
= √ 12²+7²
= √ 144+49
= √ 193
= 13,9 cm

B. panjang ag
= √ac² + cg²
= √ 193 + 100
= √ 293
= 17,1 cm
