Tolong kerjakan yang ' Uji keterampilan 4 ' berserta caranyaa yaa. - terima kasih -

1. Rumus Prisma Segitiga = La × tp
Luas = La × t
= a × t × t : 2
= 3 × 4 × 10 : 2
= 60 cm²
2. Rumus Tabung = La × t
Luas = La × t
= phi × r² × t
= 3,14 × 4 × 4 × 30
= 1507.2 cm²
3. Rumus Balok = La × t
Luas = La × t
= P × l × t
= 10 × 5 × 6 = 300 cm²
4. Rumus Kerucut = 1/3 × La × t
5. Rumus Kubus = s³
Luas = s³ = s × s × s
= 4³ = 4 × 4 × 4
= 64 cm²
6. Rumus Limas = 1/3 × La × t

maaf no 4, 6 kurang paham, maaf jika salah.....

*La = Luas Alas
