Answer :
Final answer:
Option (a) 3/4 x 5 1/2 inches, the actual size of 1x6 lumber is 3/4 x 5 1/2 inches. To convert "two-by-four" lumber to metric, its dimensions are 3.81 cm x 8.89 cm x 2.44 m. Studs placed 16.0 inches apart are equivalent to 40.64 cm apart in centimeters.
Explanation:
The actual size of 1x6 lumber is a) 3/4 x 5 1/2 inches. This measurement reflects the nominal size, which is the size of the lumber before it is dried and planed; the actual size is somewhat smaller due to this finishing process.
For part (a) of your question, tconvert the dimensions of "two-by-four" lumber from inches and feet to centimeters and meters, you use the conversion 1 inch = 2.54 cm and 1 foot = 0.3048 meters. So, the thickness is 1.50 inches x 2.54 cm/inch = 3.81 cm, the width is 3.50 inches x 2.54 cm/inch = 8.89 cm, and the length is 8.00 feet x 0.3048 meters/foot = 2.44 meters. The dimensions in metric units are 3.81 cm x 8.89 cm x 2.44 m.
For part (b), to find the distance in centimeters when studs are placed 16.0 inches apart, you multiply 16.0 inches by 2.54 cm/inch to get 40.64 cm.
