Answer :
Daedalus, Icarus, and Philo used 12,000 feathers in all using arithmetic operations.
What is multiplication and addition?
A method of calculating the product of two or more numbers is multiplication. It is one of the fundamental operations in mathematics.
In math, addition is the process of summing two or more numbers together.
Given:
Weight of Daedalus' wings = 2 kg
Weight of Icarus's wings = 1/2 of (Weight of Daedalus' wigs)
Weight of Philo's wings = 1/2 of (Weight of Icarus's wings)
Given that Daedalus, Icarus, and Philo used 2 feathers for each gram of wing.
Feathers used by Daedalus = 2(2×1000)
= 4,000
Feathers used by Icarus = 2(1/2×4000)
= 2(2000)
= 4,000
Feathers used by Philo = 2(1/2×4000)
= 4,000
Total feathers used = 4000+4000+4000
= 12000
Therefore, they used 12,000 feathers in all.
