Hitunglah volume gabungan bangun berikut
No 1
balok v = pxlxt
= 20×5×5
= 500 cm³
kubus V = s × s ×s
= 5x5x5
= 125 cm³
sehingga V = 500 +125 = 625 cm²
1.Volume kubus = S×S×S
= 5 × 5 ×
=125 cm*3
Volume balok = p×l×t
=20 × 5 × 5
=500 cm*3
Volume total = 125+500 = 625 cm*3
2.Volume tabung = Luas alas × tinggi
= π×r*2 × t
=22/7 × 21 × 21 × 24
=33264 cm*3
Volume bola = 4/3 ×π ×r*3
= 4/3 × 22/7 × 21*3
=38808 cm*3
Volume total = 33264+38808= 72072 cm*3
3.Volume tabung = Luas alas × tinggi
= π×r*2 × t
= 22/7 × 14*2 × 30
=18480 cm*3
Volume kerucut = 1/3× π × r*2 × t
=1/3 × 22/7 × 14*2 × 33
=6776 cm*3
Volume total =18480 + 6776 = 25256 cm*3
