Volume Prisma = Luas Alas x tinggi
4. a. V = L x t = 23 x 15 = 345 m3
b. t = V / L = 300 / 15 = 20 cm
c. L = V / t = 165 / 11 = 15 cm2
d. V = L x t = 19 x 8 = 152 cm3
e. t = V / L = 225 / 45 = 5 cm
Volume limas = 1/3 x luas alas x tinggi
5. a. t = 3 x V / L = 3 x 330 / 90 = 11 cm
b. V = 1/3 x L x t = 1/3 x 252 x 12 = 1.008 cm3
c. L = 3 x V / t = 3 x 312 / 13 = 72 cm2
d. t = 3 x V / L = 3 x 900 / 180 = 15 cm
e. V = 1/3 x L x t = 1/3 x 163 x 36 = 1.956 cm3
