Question

boleh bantuu nomor 11 dan 12 X)​

Answer 1

11. V1 = 10 × 10 × 10

= 1000 cm3

V2 = 14 × 10 × 17

= 2380 cm3

V gabungan = 1000 cm3 + 2380 cm3

= 3380 cm3

Jawaban: D.

12. P = 120 cm

L = 3/4 m = 0,75 m = 75 cm

T = 80 cm

• V = 120 × 75 × 80
• V = 720.000 cm3

Telah terisi 1/3 bagian

1/3 × 720.000 = 240.000 cm3

240.000 cm3 = 240 Liter

Jawaban: C.

Answer 2

Jawaban:

11. D

12. C

Penjelasan dengan langkah-langkah:

11.

Vkubus

= s×s×s

= 10×10×10

= 1.000cm3

Vbalok

= p×l×t

= 14×17×10

= 2.380cm3

Vgabungan

= 1.000+2.380

= 3.380cm3

12.

120cm = 120cm

3/4m = 0,75m = 75cm

80cm = 80cm

V = p×l×t

= 120×75×80

= 720.000cm3

= 720.000cm3 = 720liter

terisi 1/3

= 1/3 × 720

= 240 liter
