We have the following equation:
 D = m / V
 Where,
 m: mass
 V: volume
 D: density.
 The volume of the rectangular prism is:
 V = (5) * (10) * (8)
 V = 400 cm ^ 3
 For Lead:
 m = D * V
 m = (11.36) * (400)
 m = 4544 grams
 For Iron:
 m = D * V
 m = (7.87) * (400)
 m = 3148 grams
 The difference of the masses is:
 4544 - 3148 = 1396 grams
 Answer:
 
The mass of the prism made of lead is 1396 grams than the one made of iron

The Latin root word that means "stranger/enemy" is
Airida [17]

Answer:Latin hostis

Step-by-step explanation:

gostĭ is “guest,” whereas that of Latin hostis is “enemy.” To explain the connection between “guest” and “enemy” it is usually supposed that both derived their meaning from “stranger,” a sense which is still attested in Latin. The notion “favorable stranger” developed to “guest”; that of “hostile stranger” to “enemy.”
