The weight of an ant averages about 3 × 10^-⁶ kg. There are about 1 × 10²⁶ ants in the world. What is the approximate weight in kilograms of all ants in the world? Write the answer in scientific notation.

1 answer

To find the approximate weight of all ants in the world, we can multiply the average weight of an ant by the total number of ants.

Average weight of an ant = 3 × 10^-6 kg
Total number of ants = 1 × 10^26

Weight of all ants = (3 × 10^-6 kg) * (1 × 10^26 ants)

Multiplying the numbers, we get:

Weight of all ants = 3 × 10^(26 - 6) kg
= 3 × 10^20 kg

Therefore, the approximate weight of all ants in the world is 3 × 10^20 kilograms.
