tolong yaa buat pr my adek

3 . CARA 1 :
. volume = luas alas × tinggi prisma
18.050 cm^3 = luas alas × 50
luas alas = 18.050 : 50
luas alas = 361 cm^2 .

luas = 1/2 × a × t
361 = 1/2 × 38 × t
t = 361 : ( 1/2 × 38 )
t = 361 : 19
t = 19 .

CARA 2 .

volume = 1/2 × a × t1 × t2
18.050 = 1/2 × 38 × t1 × 50
t1 = 18.050 : ( 1/2 × 38 × 50 )
t1 = 18.050 : 950
t1 = 19 .

** CARA BEDA , JAWABAN SAMA **

semoga membantu .....*_* ^_^ ....
