Assuming the money is in $100 USD notes. Ksh. 17 billion is $170,000,000 which is equal to 1.7 million 100 dollar bills.
One 100 dollar bill is 1g which means 1,000 bills = 1kg
1,700,000 bills = 1,700kg
One 100 bill is 2.61 inches wide by 6.14 inches long by 0.0043 inches thick.
1.7 million bills is 117,145.674 cubic inches which is about 1.9 cubic metres.
This money can carried in one pickup.
If however the money is in Kenya shillings then the load would more than 10 times a s big because the biggest denomination is Ksh.1000 which is bou $10 dollars and the thousand shilling note is bigger than the 100 dollar note.
It would weigh more than 17 tonnes. You would need a lorry with a trailer.
