1. CONCRETE IS USED FOR THE FOUNDATIONS, PORCHES AND DRIVEWAYS, TO NAME A FEW OF THE APPLICATIONS. 5. 6. CONCRETE AND BLOCK 2. CONCRETE IS MEASURED IN CUBIC YARDS, DEPTH

TIMES SQUARE FEET. 3. A HOUSE FOUNDATION OR FOOTER IS USUALLY BY RULE OF THUMB THE THICKNESS OF THE WALL AND TWICE AS WIDE AS THE WALL. 4. FOR EXAMPLE, A WALL THAT IS 8" WIDE WILL HAVE A FOOTER WITH A HEIGHT OF 8" AND A WIDTH OF 16". THERE IS 4" ADDED TO THE INSIDE OF THE WALL AND OUTSIDE OF THE WALL TO REACH THE 16'. A FOUNDATION WALL IS MEASURED ON THE OUTSIDE. FOR A CONCRETE FLOOR, THE WALL WIDTH MUST BE SUBTRACTED TWICE FROM THE OVERALL LENGTH AND OVERALL WIDTH TO GET THE AREA OF THE FLOOR TO BE POURED. THEN USE LENGTH TIMES WIDTH TIMES .333 FEET (FOUR INCHES IN DECIMAL OF A FOOT) FOR CUBIC FEET OF CONCRETE. 7. 8. NAME: BASEMENT FLOORS ARE USUALLY 4" THICK. CINDER BLOCK ARE USUALLY EIGHT INCHES HIGH NOMINALLY, 16" LONG NOMINALLY AND VARY IN DEPTH FROM 4" UP TO 16" NOMINALLY. QUESTIONS: 9. THE NUMBER OF BLOCKS ARE DETERMINED BY LENGTH TIMES HEIGHT OF WALL TIMES.88. (.88 OF A FOOT IS THE SQUARE AREA OF A CINDER BLOCK. 10. A ROW OF BLOCKS ARE CALLED A COURSE. 11. BASEMENT WALLS ARE USUALLY THIRTEEN COURSES HIGH. 12. ONE COURSE IS USUALLY EATEN UP WITH 4" OF GRAVEL AND FOUR INCHES OF CONCRETE. 1. HOW MANY CUBIC FEET IN A CUBIC YARD? 2. CUBIC INCHES A CUBIC FOOT? 3. A CUBIC YARD OF CONCRETE WILL COVER HOW MANY SQUARE FEET, IF THE FLOOR IS TO BE 4" THICK? 4. WHAT IS THE ACTUAL SIZE OF A BLOCK THAT IS 16" X 8" X 8" NOMINALLY? LENGTH HEIGHT DEPTH 5. GIVEN A FOUNDATION WALL THAT IS 20 FEET LONG AND 16 FEET WIDE AND USES 8" BLOCK WILL REQUIRE HOW MANY YARDS OF CONCRETE FOR THE FOOTER. 6. WHERE AND WHAT DOES .88 REPRESENT? 7. THERE WILL BE 13 COURSES OF BLOCK USED FOR THE FOUNDATION WALL. HOW MANY BLOCKS DOES IT TAKE TO MAKE THE FOUR SIDES OF THE FOUNDATION WALL? 8. WHAT IS THE HEIGHT OF THE WALL WITH 13 COURSES? 9. WHAT IS THE SQUARE FOOTAGE OF THE BASEMENT FLOOR FROM THE DIMENSIONS GIVEN ABOVE? HOW MANY YARDS OF CONCRETE WILL IT TAKE TO POUR THE FLOOR? 10. WEIGHT OF A CUBIC YARD OF CONCRETE? USE THE SMITH HOUSE FOR THE NEXT THREE QUESTIONS. THE HOUSE FOUNDATION HAS 13 COURSES AND THE UNEXCAVATED AREAS WILL HAVE 6 COURSES OF BLOCK. 11. HOW MANY BLOCKS ARE REQUIRED FOR THE EXCAVATED AREA? 12. YARDS OF CONCRETE REQUIRED FOR BASEMENT FLOOR? (4” THICK) 13. YARDS OF CONCRETE FOR THE GARAGE FLOOR? (6" THICK) 14. YARDS OF CONCRETE FOR THE BASEMENT FOOTER? 15. YARDS OF CONCRETE FOR THE GARAGE FLOOR?
