Jawaban:
1. a) kubus
b)
[tex] lp \: = 6.s {}^{2} \\= 6.8 {}^{2} \\= 384cm {}^{2} [/tex]
c)
[tex]v = r {}^{3} \\= 8 {}^{3} \\=512cm {}^{3} [/tex]
2. a) balok
b)
[tex]lp = 2.(p \times l + p \times t + l \times t) \\ = 2.(19 \times 7 + 19 \times 13 + 7 \times 13) \\ = 2.471 \\ = 942cm {}^{2} [/tex]
c)
[tex]v = p.l.t \\ = 19.7.13 \\ = 1729cm {}^{3} [/tex]
3.
[tex]lp = 6.s {}^{2} \\ = 6.39 {}^{2} \\ = 9126cm {}^{2} [/tex]
4.
[tex]v = p.l.t \\ = 120.80.65 \\ = 624000cm {}^{3} [/tex]
5.
[tex]lp = 6.s {}^{2} \\ 1944 = 6.s {}^{2} \\s {}^{2} = 144 \div 6 \\ s {}^{2} = 324 \\ s = 18cm[/tex]
6.
[tex]v = r {}^{3} \\ 12.167 = r {}^{3} \\ r {}^{3} = 12.167 \\ r = 23cm [/tex]
