How many inches are there in a cubic foot?
1,728

Divide the Barge Volume by the # of cubic inches in a
cubit foot

24 cu. in. / 1728 = .013 cubic feet

The weight of water
64 pounds per cubic foot
![Page 7: Calculating Buoyancy (# Pennies) Penny Barge Design Mr. Yersak Livingston High School Technology & Design I.](https://reader035.fdocuments.net/reader035/viewer/2022062515/56649d095503460f949daf8d/html5/thumbnails/7.jpg)
Determine the pounds of water displaced by the
barge.
=.832 pounds displaced
HOW TO:• .013 cubic feet x 64 lbs. per
c^3 ft.

Grams in a Pound?
1 pound = 453.6 grams
![Page 10: Calculating Buoyancy (# Pennies) Penny Barge Design Mr. Yersak Livingston High School Technology & Design I.](https://reader035.fdocuments.net/reader035/viewer/2022062515/56649d095503460f949daf8d/html5/thumbnails/10.jpg)
Convert grams to pounds

3”.22 pounds
HOW TO:• 100 / 453.6 = .22 pounds

Subtract weight of barge from weight of displaced water to
find penny load
HOW TO:• .832- .22
= .612 pounds of pennies
![Page 12: Calculating Buoyancy (# Pennies) Penny Barge Design Mr. Yersak Livingston High School Technology & Design I.](https://reader035.fdocuments.net/reader035/viewer/2022062515/56649d095503460f949daf8d/html5/thumbnails/12.jpg)
Convert penny load lbs. into mass:
HOW TO:• .612 x 453.6
= 277 grams of pennies
![Page 13: Calculating Buoyancy (# Pennies) Penny Barge Design Mr. Yersak Livingston High School Technology & Design I.](https://reader035.fdocuments.net/reader035/viewer/2022062515/56649d095503460f949daf8d/html5/thumbnails/13.jpg)
What is the mass of a penny?
2.78 grams
![Page 14: Calculating Buoyancy (# Pennies) Penny Barge Design Mr. Yersak Livingston High School Technology & Design I.](https://reader035.fdocuments.net/reader035/viewer/2022062515/56649d095503460f949daf8d/html5/thumbnails/14.jpg)
Estimated pennies the barge can hold.
HOW TO:• 277 grams of pennies / 2.78
mass of pennies
= 99 pennies
