Tolong ya bwt bsk,,,
PLEASE,.,.,.,.
sama carax ,,,,

Answer 1

1)a. V.prisma = luas alas x tinggi
luas alas = a x t :2
= 10cm x 15cm :2
=75 cm
tinggi = 24 cm

=75 x 24
=1800 cm3
b.V.prisma = luas alas x tinggi
luas alas = a x t :2
= 9cm x 18cm :2
=81cm
tinggi = 15 cm

=81 x 15
=1215 cm3
c.V.prisma = luas alas x tinggi
luas alas = a x t :2
= 20cm x 13cm : 2
=130cm
tinggi = 26 cm

=130 x 26
=3380 cm3

2. V.prisma = luas alas x tinggi
270 =27 x tinggi
27 x tinggi = 270
tinggi = 270:27
tinggi = 10 cm

3. A. luas alas = a x t :2
= 20 cm x 12 : 2
= 120 cm
B. V.prisma = luas alas x tinggi
=120 cm x 15
=1800 cm3
