Question

An empty carton weighs 1.2kg.When packed with 24 books its total mass is 7.2kg,what is the mass of one book?​

Answer 1

one book = 0.25 kg (or 250 g)

Explanation:

total mass of books = total mass - mass of empty carton

⇒ 7.2 - 1.2 = 6 kg

Mass of one books = total mass of books ÷ total number of books

⇒ 6 ÷ 24 = 0.25kg (250 g)

Answer 2

mass of one book: 0.25 kg or 250 grams

Explanation:

mass of all books = packed carton weigh - empty carton weight

mass of all books = 7.2 - 1.2

mass of all books = 6 kg

so if 24 books weight 6 kg

1 book will weigh (6/24) → 0.25 kg or 250 grams.
