Answer:
8 pounds
Step-by-step explanation:
3 ft board = 2lb
12 ft board is 4 times more so
2x4 = 8 lb
The volume of a cube is s^3, where s is the length of a side.
If you have 84 cubes with sides of 1/3 in, the total volume is:
V=84(1/3)^3 in^3
V=84/27 in^3
V=28/9 in^3
V≈3.11 in^3 (to nearest hundredth of a cubic inch)
