tolong bantu dong skrg pliss(pke cara ya)

volume balok = panjang×lebar×tinggi
=15×8×6
=720

volume limas= 1/3 × luas alas ×tinggi
= 1/3 × (15×8) ×10
=1/3 × 120 ×10
=40×10
=400

volume bangun= v. balok +v. limas
=720+400
= b. 1120

V balok = p x l x t
= 15 x 8 x 6
= 720 cm³

La = p x l
La = 15 x 8
La = 120 cm²

V Limas = 1/3 x La x t
V Limas = 1/3 x 120 x 10
V Limas = 400 cm³

V = V balok + V Limas
V = 720 + 400
V = 1.120 cm³
Jadi, jawabannya b
