Question

Two pieces of 1 1/4" x 10" x 8' long boards equal:

A) 5 board feet
B) 13.33 board feet
C) 16.67 board feet
D) 200 board feet

Answer 1

The total board feet for two pieces of
`1 1/4` long boards is
`166.67` board feet. Option C)
`166.67`board feet is the correct choice. Additionally, 16 inches equal to
`40.64` centimeters.

Step-by-step explanation:

To calculate the total board feet of two pieces of
`1 1/4` long boards, we first need to understand the formula for board feet which is:

Board Feet = (Thickness in inches) x (Width in inches) x (Length in feet) / 12

Substituting the given values, we have:

`Board Feet = (1.25) x (10) x (8) / 12`

Multiplying the values gives:

`Board Feet = (1.25) x (10) x (8) / 12 = 83.333`

This result is for one board. Since the question asks for two boards, we double the value:

`Total Board Feet = 83.333 x 2 = 166.6666`

Rounded to two decimal places, we get
`166.67` board feet. Therefore, the answer is C)
`166.67` board feet.

Conversion from inches to centimeters:

Now, for the given side information regarding vertical studs being
`16.0`inches apart, the conversion to centimeters is as follows:

`1 inch = 2.54 centimeters`

Therefore,
`16 inches = 16 x 2.54 = 40.64` centimeters.
