Step-by-step explanation:

Ann makes chocolate balls for her birthday party.she has 10 chocolate bars each measuring 15 cm by 8 cm by 2cm.she melts all of them and pours the chocolate into some moulds to make chocolate balls.the capacity of each mould is 8ml. How many chocolate bars had she made?

Volume of  a chocolate = 15  * 8 * 2 = 240 cm³

Volume of 10 chocolates = 10 * 240 = 2400 cm³

1 cm³ = 1 ml

so Volume of chocolates = 2400 ml

Capacity of 1 mould = 8 ml

so Volume of 1 chocolate ball = 8 ml

Number of chocolates balls made = Total Volume / Volume of 1 chocolate

=> Number of chocolates balls made =  2400/8

=> Number of chocolates balls made = 300
