A full fruit box contains apples weighing 3kg, bananas weighing 22mg, and some mango weighing 3200g. Calculate the total weight of the box in kg.
1 mg = 10^-6 kg
1 g = 10^-3 kg
Total weight = apple weight + banana’s weight + mango’s weight
= 3kg +(2210^-6) + (320010^-3)
=6.200 kg ANS
A person walks 4 m to the park, then he walks 8200 km in the park then he returns back to home after grocery shopping and covers 720 cm, how much total distance that person covers in m?
1 km = 10^3 m
1 cm = 10^-2 m
Total distance + park distance + park walks + grocery shops
= 4m + (820010^3)m + (72010^-2)
= 8200011.2 m ANS.
