6-8 saja poinnya aku kasih dia kali lipat
Bangun ruang
- nomor 6
rusuk = 5 cm
v = s × s × s
v = 5 × 5 × 5
v = 25 × 5
v = 125 cm
v = 125 × 25
v = 3.125 cm³
v = 3,125 liter
- nomor 7
rusuk = 80
v = s × s × s
v = 80 × 80 × 80
v = 6.400 × 80
v = 512.000 cm³
v = 512 liter
- nomor 8
volume kubus besar
v = s × s × s
v = 4 × 4 × 4
v = 16 × 4
v = 64 m
v = 6.400 cm
volume kubus kecil
v = s × s × s
v = 2 × 2 × 2
v = 4 × 2
v = 8 cm
= 8 × 800
= 6.400 cm
800 kubus kecil
Jawaban:
6. Volume kubus = s³ = sisi×sisi×sisi
[tex](5 \times 5 \times 5) \times 25 \\ = 125 \times 25 \\ = 3.125 \: {cm}^{3} [/tex]
7.
[tex]80 \times 80 \times 80 = 512.000 \: {cm}^{3} [/tex]
8. 100 cm = 1 meter
[tex](400 \times 400 \times 400) \div 2 \\ = 64.000.000 \div 2 \\ = 32.000.000 \: kubus \: kecil[/tex]
