Answer 1

Jawab:

10) v = 1.620 cm³

p. alas = 18 cm

T prisma = 15 cm

v = 1/2 a x tΔ x Tprisma

1.620 = 1/2 x 18 x tΔ x 15

1.620 = 135 x tΔ

tΔ = 1.620 / 135

tΔ = 12 cm (A)

11) v = 2.470 cm³

tΔ = 10 cm

Tprisma = 26 cm

v = 1/2 x a x tΔ x Tprisma

2.470 = 1/2 x a x 10 x 26

2.470 = 130 x a

a = 2.470 / 130

a = 19 cm
