kalau gak bisa gak usah jawab!
Soal 1
Tinggi balok
= Volume ÷ ( P × L )
= 1.200 ÷ ( 15 × 10 )
= 1.200 ÷ 150
= 8 cm
Soal 2
Volume kubus
= S³ atau R³
= 8 × 8 × 8
= 512 cm³
Volume balok
= P × L × T
= 18 × 8 × 10
= 1.440 cm³
Volume gabungan
= V kubus + V balok
= 512 cm³ + 1.440 cm³
= 1.952 cm³
Soal 3
Volume kubus
= S³ atau R³
= 5 × 5 × 5
= 125 cm³
Volume balok
= P × L × T
= 9 × 5 × 16
= 720 cm³
Volume gabungan
= V kubus + V balok
= 125 cm³ + 720 cm³
= 845 cm³

Jawaban:
10.8cm
11.1.952cm³
12.1.323cm³
Penjelasan dengan langkah-langkah:
10.
[tex] \frac{v}{p \times l} \div = \frac{1.200}{15 \times 10} \div = \frac{1.200}{150} = 8cm³[/tex]
11.rumus balok volume pxlxt rumus kubus volume pxlxt atau sxsxs=persegi panjang =
18x8x10=1.440cm³ balok= 8x8x8=512cm³
1.440+512=1.952cm³
12.rumus seperti di atas v kubus=7x9x5=315cm³
v balok =7x16x9=1.008cm³=315+1008=
