Alas sbuah prisma berbentuk belah ketupat dengan pnjng diagonal msing-msing 16cm dan 12cm,tinggi prisma 12 cm mka luas permukaannya berapa??? please tlong di jwab ya
Marcell99Cari panjang sisi belah ketupat teorema Phytagoras, yakni: s = √(6² + 8²) s = √(36 + 64) s = √100 s = 10 cm
K alas = 4.s K alas = 4.10 cm K alas = 40 cm
L alas = ½ x d1 x d2 L alas = ½ x 12 cm x 16 cm L alas = 96 cm2
Lp = 2 x L alas + K alas . t L = 2 x 96 + 40 x 12 L = 192 + 480 L = 672 cm²
s = √(6² + 8²)
s = √(36 + 64)
s = √100
s = 10 cm
K alas = 4.s
K alas = 4.10 cm
K alas = 40 cm
L alas = ½ x d1 x d2
L alas = ½ x 12 cm x 16 cm
L alas = 96 cm2
Lp = 2 x L alas + K alas . t
L = 2 x 96 + 40 x 12
L = 192 + 480
L = 672 cm²
