soal ada di gambar ya pake cara
Materi : Bangun Ruang Sisi Datar
Luas Permukaan Bangun diatas
Lp = 5( sisi² ) + 2( pt + lt ) + pl + ( pl - sisi² )
Lp = 5( 9² ) + 2( 22.12 + 9.12 ) + 22.9 + ( 22.9 - 9² )
Lp = 5( 81 ) + 2( 264 + 108 ) + 198 + ( 198 - 81 )
Lp = 405 + 2( 372 ) + 198 + 117
Lp = 405 cm² + 744 cm² + 315 cm²
Lp = 720 cm² + 744 cm²
{ Lp = 1.464 cm² }
Semoga bisa membantu
