Nomor 3.

t = v ÷ la x 3

= 640 ÷ (1/2 x d1 x d2) x 3

= 640 ÷ (1/2 x 16 x 12) x 3

= 640 ÷ 96 x 3

= 6,67 x 3

= 20 cm

Nomor 4.

s alas = √(100 x 3 ÷ 12)

= √300 ÷ 12

= √25

= 5 cm

Nomor 5.

v = 1/3 x la x t

= 1/3 x ((1/2 x (5+8) x 6) x 10

= 1/3 x ((1/2 x 13 x 6) x 10

= 1/3 x 78 x 10

= 1/3 x 780

= 260 cm³
