We are given : The mass of a grain of sand = 
Bag contains = 10 kilograms of sand.
Let us concert 10 kg into grams first.
1 kg = 1000 grams.
10 kg = 10 × 1000 = 10000 grams = 10^4.
Therefore, bag contains 10^4 grams of sand.
Therefore, number of grains of sand are in the bag of sand of 10^4 grams =
The mass of a grain of sand in grams ÷ The mass of a grain of sand.
=
=
Therefore, 
grains of sand are in the bag of 10kg sand.
Answer:
The answer is false
Step-by-step explanation:
" An event is certain if its probability is 100% "

Akash walked kilometers in all.
Answer:
Step-by-step explanation:
1=12=+1
V = ⁴/₃πr³
V = ⁴/₃(3.14)(6)³
V = ⁴/₃(3.14)(216)
V = ⁴/₃(678.24)
V = 904.23cm³
It is equal to 288πcm³.
