Diketahui:
Panjang prisma = 12 cm
Tinggi prisma = 35 cm
Volume prisma = 2.880 [tex]cm^{2}[/tex]
Ditanyakan:
Lebar alas prisma
Penyelesaian:
Volume prisma = Luas alas x tinggi
Volume prisma = ( p x l ) x t
2880 = ( 12 x l ) x 35
2880 = 12l x 35
2880 = 420 l
l = 2880 / 420
l = 6,857 cm
Jadi, lebar alas prisma tersebut adalah 6,857 cm.
