Answer 1

2
V prisma = 720
luas alas = 30
V prima = luas alas x tinggi prisma
t prisma = V/ L = 720/30 = 24 cm

2.
V prisma = 320
tinggi= 8 cm
Luas alas = Volume / tinggi
L alas = 32/8 = 40 cm²

Answer 2

1> alas= 1380 : 92
= 15
2> luas alas = V / t= 320 : 8
= 40
3> V tabung = 3,14 . 5^2 . 10
=785
4> V tabung=3,14 . 18^2 . 34
= 34590,24
5>r= √1848/12 . 3,14
=√483,56
=22
