Ka = a + b + c
= 20 cm + 20 cm + 20 cm
= 60 cm
S = Ka : 2
= 60 cm : 2
= 30 cm
La =

= cm²
V = La × t
= 100√3 cm² × 24 cm
= 2400√3 cm³
LP = 2(La) + (Ka × t)
= 2(100√3) + (60 × 24)
= 200√3 + 1440
= 1640√3 cm²
= 240 cm² × 24 cm = 5.760 cm³
Luas permukaan = ( 2× 240 cm) + ( 60 cm × 24 cm) = 480 cm² + 1.440 cm²
= 1.920 cm²
