Question

pakai cara dan jangan ngasal ya​

Answer 1

Penjelasan dengan langkah-langkah:

1. v balok = v kubus

p = 20 cm

l = 10 cm

t = 5 cm

v balok

= p x l x t

= 20 x 10 x 5

= 1.000 cm³

v balok = v kubus, maka

v kubus = 1.000 cm³

• cari rusuk

v = r³

1.000 = r³

r = ³√1.000

r = 10 cm

2. p¹ = 18 cm

l¹ = 5 cm

t¹ = 6 cm

p² = 12 cm

l² = 5 cm

t² = 5 cm

volume gabungan

= volume balok 1 + volume balok 2

= (p¹ x l¹ x t¹) + (p² + l² + t²)

= (18 x 5 x 6) + (12 x 5 x 5)

= 540 + 300

= 840 cm³

Answer 2

Verified answer

Jawaban:

9. Panjang rusuk kubus = 10 cm

10. Volume bangun gabungan = C. 840 cm³

Penjelasan dengan langkah-langkah:

rumus mencari volume balok = p×l×t

= 20 × 10 × 5

= 1.000 cm³

panjang rusuk kubus = ³√ Volume

= ³√ 1.000

= ³√ 10 × 10 × 10

panjang rusuk kubus = 10 cm

rumus mencari volume balok = p×l× t

= 12 × 5 × 5

= 300 cm³

Volume balok ii = 18 × 5 × 6

= 540 cm ³

Volume bangun gabungan = 300 + 540 = 840 cm³
