Luas Permukaan Kerucut :
L = πr(r + s)
L = 22/7 × 14(14 + 10)
L = 22 × 2(28)
L = 44 × 28
L = 1.232 cm²

5.
Luas Permukaan Kubus :
L = 6s²
L = 6 × 4 × 4
L = 6 × 16
L = 96 cm²

6.
Luas Alas :
L = pl
L = 10 × 5
L = 50 cm²

Luas Sisi Miring 1 :
L = ½ × a × t
L = ½ × 10 × 8
L = 10 × 4
L = 40 cm²

Luas Sisi Miring 2 :
L = ½ × a × t
L = ½ × 5 × 9
L = ½ × 45
L = 22,5 cm²

Luas Permukaan Limas :
L = La + 2 × L¹ + 2 × L²
L = 50 cm² + 2 × 40 cm² + 2 × 22,5 cm²
L = 50 cm² + 80 cm² + 45 cm²
L = 130 cm² + 45 cm²
L = 175 cm²
