Question

tolong dengan caranya juga ya kak​

Answer 1

Penjelasan dengan langkah-langkah:

BANGUN RUANG DATAR

• L I M A S

1. p = 16 cm

l = 12 cm

t = 15 cm

Volume = p × l × t/3

Volume = 16 × 12 × 15/3

Volume = 192 × 5

Volume = 960 cm³

2. d1 = 14 cm

d2 = 8 cm

t = 10 cm

Volume = d1 × d2/2 × t/3

Volume = 14 × 8/2 × 10/3

Volume = 14 × 4 × 10/3

Volume = 560/3

Volume = 186,67 cm³

3. s = 10 cm → ½s = 5 cm

t∆ = 13 cm

a) t = √(13² – 5²) = √(169 – 25) = √144 = 12 cm

b) Volume = s² × t/3

Volume = 10² × 12/3

Volume = 100 × 4

Volume = 400 cm³
