Matematika Volume prisma tersebut adalah … cm3. ​

Volume prisma tersebut adalah … cm3. ​

Penjelasan dengan langkah-langkah:

PRISMA TEGAK

BC = √(15² – 12²) = √(225 – 144)

BC = √81

BC = 9 cm

Volume = ½ × 12 × 9 × 10

Volume = 6× 90

Volume = 540 cm³

  • Menentukan prima segitiga tegak

BC² = AB² - AC²

BC² = 15² - 12²

BC² = ( 15 × 15 ) - ( 12 × 12 )

BC² = 225 - 144

BC² = 81

BC = √81

BC = 9 cm

  • Menentukan volume prisma

v = ½ × Luas alas × tinggi

v = ½ × ( 12 × 9 ) × 10

v = ½ × 108 × 10

[tex]v = \frac{108}{2} × 10 [/tex]

v = 54 × 10

v = 540 cm³
