Penjelasan dengan langkah-langkah:

1) V = p x l x t = 120 x 60 x 70 = 504.000 cm³ = 504 dm³ = 504 liter

2) V. Bak = p x l x t = 30 x 20 x 10 = 6.000 dm³

V. Gayung = p x l x t = 3 x 2 x 1 = 6 dm³

Banyak Air Yang Diambil :

= V. Bak : V. Gayung

= 6.000 dm³ : 6 dm³

= 1.000 kali

3) V = s³ = 15³ = 3.375 cm³

Banyak Pasir = ⅓ x 3.375 cm³ = 1.125 cm³

4) V = L. Alas x T. Prisma

= (½ x a x t) x T. Prisma

= (½ x 6 x 8) x 10

= 24 x 10

= 240 cm³

5) V = L. Alas x T. Prisma

= (½ x (a + b) x t) x T. Prisma

= (½ x (7 + 8) x 10) x 12

= (½ x 15 x 10) x 12

= 75 x 12

= 900 cm³

6) V = L. Alas x T. Prisma

= (½ x a x t) x T. Prisma

= (½ x 12 x 20) x 22

= 120 x 22

= 2.640 cm³

7) r = d/2 = 40/2 = 20 cm

V = πr²t = 3,14 x 20² x 15 = 18.840 cm³

8) V. Gelas A : V. Gelas B

πr1²t1 : πr2²t2 (masing² ruas π - nya dicoret)

5² x 10 : 10² x 10

250 : 1.000 (masing² ruas dibagi 250)

1 : 4
