Rumus mencari keliling Prisma segi empat :
K = 4 (p + l + t)
K = 4 (12 + 10 + 20)
K = 4 (42)
K = 168 cm
Rumus mencari luas permukaan Prisma segi empat :
L = 2 x ( (p x l) + (p x t) + (l x t) )
L = 2 x ( (12 x 10) + (12 x 20) + (10x 20) )
L = 2 x (120 + 240 + 200)
L= 2 x (560)
L = 1.120 cm2
Rumus mencari Volume prisma segiempat :
V = luas alas x tinggi
