tolong nomer 3 sama nomer 5 aja y

3.

Volume balok = 50 × 10 × 25 = 12500 cm3
Volume kubus = 5 × 5 × 5 = 125 cm3
12500 ÷ 125 = 100 buah

volume balok= 50 × 10 × 25 : 5 × 5 × 5
10×2×5 : 1×1×1
Jadi banyak kubus = 10×2×5 = 100 kubus kecil.
5) volume total = volume balok+volume kerucut.
= (25×8×10)+ (1/3.luas alas× tinggi)1
= (2.000) + (1/3.25×8× 15)
= 2.000 + 1.000
= 3.000 cm^3
