volume gabungan bangun ruang berikut adalah....cm³
Jawaban:
Volume 1
= s³
= 15³
= 3375 cm³
Volume 2
= ⅓ × Luas alas x tinggi
= ⅓ × s² × t
= ⅓ × 15² × (24-15)
= ⅓ × 225 × 9
= 675 cm³
maka totalnya
3375 + 675
= 4050 cm³
Jawaban:
tinggi limas = 24 - 15 = 9 cm
Volume bangun gabungan
[tex] = v \: kubus + v \: limas \\ = {s}^{3} + ( \frac{1}{3} \times l \: alas \times t) \\ = (15 \times 15 \times 15) + ( \frac{1}{3} \times 15 \times 15 \times 9) \\ = 3375 +( 225 \times 3) \\ = 3375 + 675 \\ = 4050 \: {cm}^{3} [/tex]
