1.tinggi balok
= volume / p . l
= 1920 /12 . 8
=1920/96
=20cm
luas balok
=tinggi . lebar
= 20. 8
= 160 cm²
2.Rumus volume prisma = L. alas x tinggi
L. alas (persegi) = s x s = 10 x 10 = 100
V. prisma = 100 x 7 = 700
3.Volume limas= 1/3 x luas alas x tinggi
= 1/3 (10x10) x 12
= 1/3:1200
= 400 cm³
maaf kalau salah
