Bantu jawab semua yang dilingkari dong pls
Langkah-langkah pengerjaan:
3. b
[tex]v \: = p \times l \times t\\ 3.960 = p \: \times 12 \times 22 \\ 3.960 = p \times 264 \\ 3.960 \div 264 = p \\ p = 3.960 \div 264 \\ p = 15 \: cm[/tex]
3. c
[tex]v = p \times l \times t \\ 5.100 = 20 \times l \times 17 \\ 5.100 = 340 \times l \\ 5.100 \div 340 = l \\ l = 5.100 \div 340 \\ l = 15 \: cm[/tex]
4.
[tex]v = luas \: alas \times t \\ v = 216 \times 15 \\ v = 3.240 \: cm {}^{3} [/tex]
Semoga membantu^^
