Diketahuii balok ABCD.EFGH dengan AB = 4cm,AD = 3 cm dan AE = 12 cm . luas bidang diagonal ACGE adalah
danuef
AB = 4cm,AD = 3 cm dan AE = 12 cm AC = GE = √4² + 3² AC = GE = √16 + 9 AC = GE = √25 AC = GE = 5 cm L = p x l L = 12 x 5 L = 60 cm² Jadi Luas Bidang ACGE = 60 cm²
AC = GE = √4² + 3²
AC = GE = √16 + 9
AC = GE = √25
AC = GE = 5 cm
L = p x l
L = 12 x 5
L = 60 cm²
Jadi Luas Bidang ACGE = 60 cm²
