Exercise 6.4

You are building a house the same house as in the example above, only the footing is

20 wide by 10 high. The foundation wall that will sit on top of the footing, 6 wide

by 3-6 tall. Calculate the volume of concrete required, and how many cubic yards

of concrete will we need to order (assuming we can order . yards)?

Exercise 6.5

What if the perimeter of the building in Exercise 6.4 above had been 166? What

would your concrete calculations look like then?

Exercise 6.6

You are constructing 4 giant cylindrical concrete columns. They each have a radius

of 1-9 and will be built to a height of 32. How much concrete will be required to

do the work?

4. 75 2x6s 10 long $1115M

5. 12 2x4 8 $3.72 each

6. 2820M 12 2x6 cedar decking 1pc

7. 230 8 2x6 stud $1150/thousand

8. 22 10 2x4s S4S 19% $790M

9. Ten 10 4x4s cedar $29.99each

10. 48 2x12 16 2750M

Paying for Sheet Goods by the Square Foot

Lumber yards price flat panel products differently. For ply and OSB and a myriad of

other available flat products, they charge contractors by the square foot, and they

ignore the thickness of the material so long as that material is 1 thick or less. In

other words, they are charging you for these goods based upon AREA, not Volume.

You will be charged a higher price for materials over 1 thick, depending upon the

seller.

Exercise 7.4

Practice Calculating Square Footage and Total Cost for the following situations:

11. Ten . x 4x10 Plywood @ 2100M

12. 15 . x 4x8 OSB @ 740M

13. 22 3x 5 x . cement board $10.46 per sheet
