tolong yaa soal prisma no. 1-4 tks

3.) L = 2 La + Ka x t
62 = 2(2x3) + 2(2+3) x t
62 = 12 + 10 x t
62 = 22 t
t = 62/ 22 = 2,82 cm

4.) b.
EF² = DF² + ED²
EF² = 8² + 6²
EF² = 64 + 36
EF² = 100
EF = √100 = 10 cm
c.
L = 2 La + Ka x t
= 2 (6x8) + (1/2 x 8 x 6) x 12
= 96 + 288
= 384 cm²
V = La x t
= (1/2 x 6 x 8) x 12
= 24 x 12
= 288 cm^3

Semoga membantu
Maaf kalau salah ya
Tapi kalau salah
Tolong jangan laporkan
Jawaban yaa
Terima Kasih
