  1. Calculating Buoyancy (# Pennies)Penny Barge Design Mr. Yersak Livingston High School Technology & Design I

  2. 2” 3” 4” Dimension your vesselLength – Width - Height

  3. 2” 3” 4” Determine the Volume of the Barge • HOW TO: • LENGTH x WIDTH x HEIGHT = VOLUME • 24 cu. in.

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

  5. 2” 3” 4” Divide the Barge Volume by the # of cubic inches in a cubit foot • 24 cu. in. / 1728 = .013 cubic feet

  6. The weight of water 64 pounds per cubic foot

  7. Determine the pounds of water displaced by the barge. • HOW TO: • .013 cubic feet x 64 lbs. per c^3 ft. =.832 pounds displaced

  8. 2” 3” 4” Determine the mass of the barge Aprox. 100 Grams

  9. Grams in a Pound? 1 pound = 453.6 grams

  10. 2” 3” 4” Convert grams to pounds .22 pounds • HOW TO: • 100 / 453.6 = .22 pounds

  11. Subtract weight of barge from weight of displaced water to find penny load • HOW TO: • .832- .22 • = .612 pounds of pennies

  12. Convert penny load lbs. into mass: • HOW TO: • .612 x 453.6 • = 277 grams of pennies

  13. What is the mass of a penny? 2.78 grams

  14. Estimated pennies the barge can hold. • HOW TO: • 277 grams of pennies / 2.78 mass of pennies • = 99 pennies
