panjang balok 35cm lebar 25cm tinggi 15 cm brp volume dan luas permukaan balok tersebut

Materi Bangun Ruang

V = p×l×t = 35×25×15 = 13.125 cm^3
Lp = 2(pl+pt+lt) = 2(35×25 + 35 × 15 + 25 × 15)
= 2(875 + 525 + 375)
= 2( 1775 ) = 3550 cm^2

p = 35 cm
l = 25 cm
t = 15 cm

Volume balok
= p x l x t
= 35 x 25 x 15
= 13.125 cm³

Luas permukaan balok
= 2pl + 2pt + 2lt
= 2(35 x 25) + 2(35 x 15) + 2(25 x 15)
= 2(875) + 2(525) + 2(375)
= 1.750 + 1.050 + 750
= 3.550 cm²
