Jawaban:
1. 3 dm
2. 8 dm
3. 20 dm
4. 12,6 dm
5. 20 cm
Penjelasan dengan langkah-langkah:
1. V = 27 liter
= 27 dm³
V = s³
27 = s³
s = ³√27
s = 3 dm
2. V = 512 liter
= 512 dm³
512 = s³
s = ³√512
s = 8 dm
Jadi kedalaman bak mandi = 8 dm
3. V = 8000 liter
= 8000
8000 = s³
s = ³√8000
s = 20 dm
Rusuknya adalah 20 dm
4. 1/2 V = 1000 dm³ | × 2 |
V = 2000 dm³
2000 = s³
s = ³√2000
s = 12,6 dm
5. 1 cm³ = 2 gram
m = 16 kg = 16000 gram
V = m : 2 × 1 cm³
= 16.000 : 2 × 1 cm³
= 8.000 cm³
8.000 = s³
s = 20 cm
