Luas prmukaan limas =luas alas +jmlh luas sisi teqak
=256+4(17)
=256+68
=324
volume limas =1 per 3×luas alas ×tinggi
=256×5
=1280cm kubit

T. segitiga = √15^2+8^2= √225+64=√289=17 cm
l.p.limas = l.alas +4. l. segitiga= (s×s)+4(1/2×a×t)=(16×16)+4(1/2×16×17)=256+(4×136)=256
+544=800 cm^2
v.limas= 1/3× l.alas× t=1/3×256×15=1280 cm^3
