15 X 10 = 150

Answer 2

Penjelasan dengan langkah-langkah:

1. p = 15 cm

l = 10 cm

t = 15 cm

v = 1/3 x La x t

v = 1/3 x p x l x t

v = 1/3 x 15 x 10 x 15

v = 150 x 5

v = 750 cm³

2. d1 = 12 cm

d2 = 16 cm

v = 640 cm³

v = 1/3 x La x t

v = 1/3 x (d1 x d2 : 2) x t

640 = 1/3 x (12 x 16 : 2) x t

640 = 1/3 x 96 x t

t = 640 : 32

t = 20 cm

3. v = 100 cm³

t = 12 cm

v = 1/3 x La x t

100 = 1/3 x La x 12

La = 100 : 4

La = 25 cm²

La = s x s

25 = s²

s = √25

s = 5 cm
