Penjelasan dengan langkah-langkah:

1) V kubus = r x r x r

= 16dm x 16dm x 16dm

= 4.096 dm3 = 4.096 liter

sisa air = 4.096 - 1.250 = 2.846 liter

2) V balok = p x l x t

V balok 1 = 5cm x 8cm x 8cm

= 320 cm3

V balok2 = 16cm x 8cm x 5cm

= 640 cm3

total Volume = 320+640= 960 cm3

3) L. satu sisi kubus berbentuk persegi

L. persegi = r x r

r pangkat 2 = 225

r = √225 = 15dm

V kubus = r x r x r

= 15dm x 15dm x 15dm

= 3.375 dm3 = 3.375 liter

4) V balok = p x l x t

= 4cm x 3cm x 7cm

= 84cm3

5) V bak = p x l x t

= 5m x 2m x 1m

= 10 m3 = 10.000 liter
