jawaban soal nomer 3 a.) volum = La x t = a²/4 √3 x 24 = 20²/4 √3 x 24 = 400/4 √3 x 24 = 100√3 x 24 = 2400 √3 b.) moho maaf gak begitu tau lagkahya mencai tingsi sisi tegak
V = p x l x t
5292 = 18 x 14 x t
5292 = 252 x t
t = 21 cm
2.b
Lp = 2(pl) + 2(pt) + 2(lt)
Lp = 2(18x14) + 2(18x21) + 2(14x21)
Lp = 501 + 756 + 588
Lp = 1845
3.a
La = 1/a x a x t
La = 1/2 x 20 x 10√3
La = 100√3
V = La x t prisma
V = 100√3 x 24
V = 2400√3
4.a
Lp = 2.La + 3.Ls
Lp = 2.100√3 + 3.(20x24)
Lp = 200√3 + 1440
a.) tinggi balok
volum = 5292
18x 14 x t = 5292
252 xt = 5292
t = 5292/252
t = 21
b.) Lp = 2 ( pxl + pxt + lxt )
= 2 ( 18x14 + 18x21 + 14x21)
= 2 ( 252 + 378 + 294 )
= 2 ( 924)
= 1848 cm²
jawaban soal nomer 3
a.) volum = La x t
= a²/4 √3 x 24
= 20²/4 √3 x 24
= 400/4 √3 x 24
= 100√3 x 24
= 2400 √3
b.) moho maaf gak begitu tau lagkahya mencai tingsi sisi tegak
