perhatikan gambar diatas,hitunglah luas permukaan prisma berikut??

13²=12²+x²
169=144+x²
√25=x
5=x
Vprisma=Lalas x t
=1/2.a.t x t
=1/2.5.12 x 11
=1/2.60 x 11
=30 x 11
=330cm²
*Moga Bermanfaat Yakk

La= 1/2×12×13
La= 78 cm^2

C^2= 13^2-12^2
C^2= 169-144
C^2= 25
C= 5 cm

Ka= 13+12+5
Ka= 30 cm

L= 2×La+Ka×t
L= 2×78+30×11
L= 156+330
L= 486 cm^2

Maaf klo salah
