Question

4. Tentukan volume prisma berikut! 8 cm 10 cm 16 cm 20 cm​

Answer 1

Penjelasan dengan langkah-langkah:

NOMOR 1

V = (8×10×20) + ((16-10)×8×20)÷2))

V = 1.600 + 480

V = 2.080 cm³

NOMOR 2

V = ((25×40×30)) + ((45-25))×30/2)×40))

V = 30.000 + 12.000

V = 42.000 cm³

Answer 2

Verified answer

1. Volume

V = La × t

V = (16 + 10)/2 × 8 × 20

V = 26 × 4 × 20

V = 26 × 80

V = 2.080 cm³

2. Volume gabungan

V = La × t + p × l × t

V = 40 × 30 × 20/2 + 40 × 30 × 25

V = 40 × 30 × 20 + 1.200 × 25

V = 24.000/2 + 30.000

V = 12.000 + 30.000

V = 42.000 cm³
