= 4.(16+18+12)
= 4.46
= 184 cm
5) diagonal ruang = s√3 = 10√3 cm
6) diagonal ruang = s√3
√48 = s√3
√16.3 = s√3
4√3 = s√3
s = 4 cm
7). maap blm kjawab
= 184 cm
5.) Diagonal Ruang Kubus = r√3
= 10√3 cm
6.) Diagonal Kubus = r√2
√48 = r√2
r = √48
√2
r = √24 cm
r = √4.6 cm
r = 2√6 cm
7.) AC² = AB² + BC²
= 16² + 12²
= 256 + 144
= 400
AC = √400
= 20 cm
Luas Bidang ACGE = Luas Bidang Diagonal
Luas Bidang ACGE = AC x AE
= 20 x 15
= 300 cm²
