Now let me show you how to calculate board feet lumber and costs on your
Construction Master Pro.
Keep in mind the keystrokes will be exactly the same if you're using the trig or
the desktop model.
The board foot function handles unitless entries just the way you say them.
For example, 2 x 4 x 8.
Say we need 20 pieces of 2 x 4 x 12.
The way to enter that that is
[2] [x] [4] [x] [1][2]
[Conv] over the [8] key it says Bd Ft, the second function.
So a 2 x 4 x 12 is 8 board feet. Say I need 20 of those.
[x] [2][0]
equals 160 board feet. Let's put that in the memory.
And I need 30 pieces of 2 x 6 x 20.
[2] [x] [6] [x] [2][0]
[Conv]
board feet
and I need 30 pieces of that.
[x] [3][0] equals 600 board feet. Put that in the memory. Now I can recall
what's in the memory.
So we have a total of 760 board feet. Say this particular material
goes for $375 dollars per thousand board feet. So I would say
[x] [3][7][5] [Conv]
over the [0] key is the cost function.
So that would be $285 worth of lumber.
You can also calculate board feet as a cubic volume number.
We know that a board foot is 144 cubic inches. Say you've
got a 2 inch
by 4 inch by 12
twelve feet board.
You've got
cubic yards which is really irrelevant in this example. Convert that
to cubic inches if you like,
but more appropriately is convert to board feet. So the same 8 board feet.
So that's a quick overview on the board feet lumber function. For more details you can
