t = 20 cm

Volume Balok?
Luas Permukaan Balok?

Pke cra...
​

Penjelasan dengan langkah-langkah:

P : 30 cm

L : 15 cm

T : 20 cm

V balok : p x l x t

V balok : 30 x 15 x 20

V balok : 450 x 20

V balok : 9.000 cm³

Lp balok : 2( p × l) + (p × t) + (l × t)

Lp balok : 2(30 × 15) + (30 × 20) + (15 × 20)

Lp balok : 2( 450 + 600 + 300)

Lp balok : 2(1350)

Lp balok :2.700 cm²

Penyelesaian:

P=30cm

L=15cm

T=20cm

----------------------------------------

V=P.L.T

V=30×15×20

V=450×20

V=9.000cm³

----------------------------------------

Lp=2(p.l+p.t+l.t)

Lp=2(30.15+30.20+15.20)

Lp=2(450+600+300)

Lp=2(450+900)

Lp=2(1.350)

Lp=2.700cm²
