1. Volum Balok = P x L x T
= 80 x 40 x 50
= 160.000 cm³
2. Volum Kubus = S x S x S
= 50 x 50 x 50
= 125.000 cm³
3. Volum Limas = 1/3 x L alas x Tinggi
= 1/3 x (1/2 x a x t ) x Tinggi
= 1/3 x (1/2 x 40 x 30 ) x 20
= 1/3 x 600 x 20
= 4.000 cm³
4. Volum Prisma = Luas alas x Tinggi
= (1/2 x a x t ) x Tinggi
= (1/2 x 40 x 60 ) x 80
= 1.200 x 80
= 96.000 cm³
5. Volum Prisma = 1/2 x l alas x tinggi
= 1/2 x (1/2 x 8 x 6 ) x 18
= 1/2 x 24 x 18
= 216 cm³
6. Volum Prisma Trapesium = 1/2 x l alas x t
= 1/2 x (1/2 x (5 + 3) x 3 ) x 8
= 48 cm³
7. Volum Balok = p x l x t Volum Limas = 1/3 x L alas x t
= 6 x 5 x 4 = 1/3 x (6 x 5) x 7
= 120 cm³ = 1/3 x 30 x 7
= 70 cm³
Volum gabungan = 120 + 70 = 190 cm³
