Question

Alas Prisma berbentuk belah ketupat dgn pjang diagonal 12 cm dan 10 cm. Ketahui tinggi prisma 24 cm

yg nggak jawab Moga Pantaknya Bisulan​

Answer 1

d1 = 12 cm

d2 = 10 cm

t = 24 cm

V = 1/2 × d1 × d2 × t

V = 1/2 × 12 × 10 × 24

V = 1440 cm³

s = V[(d1/2)² + (d2/2)²]

s = V[(12/2)² + (10/2)²]

s = V(6² + 5²)

s = V(36 + 25)

s = V61

s = 7,8 cm

K = 4 × s

K = 4 × 7,8

K = 31,2 cm

L = (2 × 1/2 × d1 × d2) + (K × t)

L = (2 × 1/2 × 12 × 10) + (31,2 × 24)

L = 120 + 748,8

L = 868,8 cm²
