Tentukan volume kubus berikut

Jawaban:

1. a. V= s x s x s = 12 x 12 x 12 = 1.728cm³

b. V= s x s x s = 4 x 4 x 4 = 64cm³

kenapa pake 4?? w harap lu bisa pikir sendiri

2. L.alas=S²

81= S²

S= √81

S= 9cm

V= 9x9x9 = 729cm³

3. Pjg rusuk = sisi

V= S³

4.913= S³

S = ³√4.913 cm

4. Total rusuk kubus = 12rusuk

252/12 = 21cm

V= 21x21x21 = 9.261cm³
