Answer 1

3) dik= Limas alas prsegi
s=10cm
t= 12cm
dit= Lp?
Lp = La+ jumlah sisi tegak
= s2 + 4. a.t/2
= 102 + 4. 10.t/2
1/2 dri alas = 1/2. 10 = 5
tggi bidang tegak = akar 5kuadrat + 12kuadrat = akar 25 + 144 = akar 169 = 13cm.
Lp= (10)2 + 4. 10.13/2
= 100 + 260
= 360cm2
14) V= p.l.t
= 28cm.16cm.78cm
= 34944cm3
10) V= La.t
= p.l.t
= 17cm. 12cm. 10cm
= 2040cm3.
cuman itu yg saya tau kak.
