6 ways:


4 ft X 6 = 24 ft (6 pieces of 4 ft long lumber)


6 ft x 4 = 24 ft (4 pieces of 6 ft long lumber)


12 ft x 2 = 24 ft (2 pieces of 12 ft long lumber)


6 ft x 2 + 12 ft = 24 ft (2 pieces of 6 ft long lumber and 1 piece of 12 ft long lumber)


4 ft x 3 + 12 ft = 24 ft (3 pieces of 4 ft long lumber and 1 piece of 12 ft long lumber)


4 ft x 3 + 6 ft x 2 = 24 ft (3 pieces of 4 ft long lumber and 2 piece of 6 ft long lumber)
