56 = 4s
56/4 = s
14 =s
sisi miring = 1/2 sisi + tinggi
= 7² + 24²
= √625
= 25
Luas permukaan = alas + 4 segitiga
LP Limas = 14 x 14 + 4 x 1/2 x 14 x 25
=196 + 700

56 = 4s
14 = s
tinggi segitiga = (1/2 x 14)² + 24²
= √49 + 576
=√625
= 25 cm
Luas Permukaan Limas = Luas Alas + 4 Luas Segitiga
= 14 x 14 + 4 x 1/2 x 14 x 25
= 196 + 700
= 896 cm²
