Volume Limas = P x L x T = 24 x 60 x 16 = 23.040 cm Luas Limas = P x L = 24 x 60 = 1.440

Luas alas = p x l = 24 x 60 = 1440cm² Keliling = 2 ( p + l ) = 2 ( 24 + 60 ) = 2 x 84 = 168cm a) Volume = 1/3 x L.alas x tinggi = 1/3 x 1440 x 16 = 7.680cm³ b) s = √ 16² + 12² = √ 256 + 144 = √ 400 = 20cm Lp = L.alas + 1/2 x K.alas x s = 1440 + 1/2 x 168 x 20 = 1440 + 1680 = 3120cm²
Luas Limas = P x L = 24 x 60 = 1.440
= 24 x 60
= 1440cm²
Keliling = 2 ( p + l )
= 2 ( 24 + 60 )
= 2 x 84
= 168cm
a) Volume = 1/3 x L.alas x tinggi
= 1/3 x 1440 x 16
= 7.680cm³
b) s = √ 16² + 12²
= √ 256 + 144
= √ 400
= 20cm
Lp = L.alas + 1/2 x K.alas x s
= 1440 + 1/2 x 168 x 20
= 1440 + 1680
= 3120cm²
