Penjelasan dengan langkah-langkah:

1.

³√ 27.000 = 30

³√13.824 = 24

selisih = 30 - 24 = 6cm

2.

volume= PLT

1 liter = 1dm³

V = 150 × 75 × 84

= 945.000cm³ = 945dm³

1 ember = 5 liter

945 ÷ 5 = 189 ember

3.

volume = r³

= 30³ = 27.000cm³

27.000 × 5 = 135.000cm³

4.

2/3 = 1.728 liter

3/3 = 1.728 × 3/2 = 2.592 liter

p = 4l

t = 3l

2.592 = 4l × l × 3l

2.592 = 12l³

l³ = 2.592 ÷ 12

l³ = 216

l = ³√216

l = 6dm

p = 4l = 4(6) = 24dm

t = 3l = 3(6) = 18dm

5.

18³ = 5.832cm

1/2 × 5.832 = 2.916

l = 2.916 ÷ (27× 12)

= 2.916 ÷ 324 = 9cm

6.

V = 56 × 32 × 24 = 43.008cm³

V = 4³ = 64cm³

43.008 ÷ 64 = 672 kubus

7.

V = 75 × 60 × 35 = 157.500cm³ = 157,5dm³ = 157,5 liter

8

V = 45 × 30 × 35 = 47.250 cm³ = 47,25 liter

47,25 - 27 = 20,25 liter

9

30³ = 27.000cm³ = 27 liter

35³ = 42.875cm³ = 42,875 liter

42,875 - 27 = 15,875 liter air yang tumpah

10.

2³ = 8m³ = 8000dm³ = 8000 liter

8.000 × 400 = 3.200.000
