tlg ya kak dengan penjelasan​

Answer 1

Catatan:

lebar balok = volume balok ÷ (panjang × tinggi)

Jawaban dengan cara:

1. 7 cm, cara:

lebar = 378 ÷ (9×6)

lebar = 378 ÷ 54

lebar = 7

2. 12 cm, cara:

9 = 1188 ÷ (11×t)

9 = 1188 ÷ 11t

pindah ruas

11t = 1188 ÷ 9

11t = 132

t = 132÷11

t = 12

3. 14 cm, cara:

8 = 1120 ÷ (p×10)

8 = 1120 ÷ 10p

pindah ruas

10p = 1120 ÷ 8

10p = 140

p = 140 ÷ 10

p = 14

4. 6 cm, cara:

lebar = 810 ÷ (15×9)

lebar = 810 ÷ 135

lebar = 6

5. 14 cm, cara:

7 = 1666 ÷ (17×t)

7 = 1666 ÷ 17t

pindah ruas

17t = 1666 ÷ 7

17t = 238

t = 238 ÷ 17

t = 14

6. 9 cm, cara:

lebar = 2430 ÷ (18×15)

lebar = 2430 ÷ 270

lebar = 9

7. 7 cm, cara:

9 = 1260 ÷ (20×t)

9 = 1260 ÷ 20t

pindah ruas

20t = 1260 ÷ 9

20t = 140

t = 140 ÷ 20

t = 7

8. 12 cm, cara:

10 = 840 ÷ (p×7)

10 = 840 ÷ 7p

pindah ruas

7p = 840 ÷ 10

7p = 84

p = 84 ÷ 7

p = 12

9. 9 cm, cara:

lebar = 1584 ÷ (22×8)

lebar = 1584 ÷ 176

lebar = 9

10. 18 cm, cara:

7 = 1512 ÷ (p×12)

7 = 1512 ÷ 12p

pindah ruas

12p = 1512 ÷ 7

12p = 216

p = 216 ÷ 12

p = 18 cm
