Jawaban:
4.284 cm³
Penjelasan dengan langkah-langkah:
Rumus: S × S × S
V = 20 × 20 × 20
= 8.000 cm³
Rumus: ( π × r ) × r × t
V = ( 22/7 × 10 ) × 10 × 12
= 22 × 1.4285714286 × 10 × 12
= 3,771.4285715 cm³
r : d (s) × ½ = 20 × ½ = 10
Rumus: hasil a + hasil b
V = 8,000 + 3,771.4285715 = 11,771.428572 cm³

Penjelasan dengan langkah-langkah:
A. Volume kubus (a)
Rumus: S × S × S
V = 20 × 20 × 20
= 8.000 cm³
B. Volume tabung (b)
Rumus: ( π × r ) × r × t
V = ( 22/7 × 10 ) × 10 × 12
= 22 × 1.4285714286 × 10 × 12
= 3,771.4285715 cm³
r : d (s) × ½ = 20 × ½ = 10
C. Volume seluruhnya
Rumus: hasil a + hasil b
V = 8,000 + 3,771.4285715 = 11,771.428572 cm³
