2. Using the geometric method determine the amount of excavation required for the basement in below Figure 2. The basement measurements are from the outside of the foundation walls. The average depth of the excavation is 7 feet. The footings extend 1 foot outside of the foundation walls, and a 2-foot space between the footing and the sides of the excavation must be provided to form the footings. The soil is excavated at a 1.5:1 (horizontal:vertical) slope. Express your answer in cubic yards.

3. The perimeter of the floor system in below Figure 3 sits on a redwood sill. Determine the number of 16-foot-long pieces of redwood that are needed to complete the floor system. Determine the materials needed to construct the joists and joist headers for the floor system. An engineered rim board is used for the joist headers. Determine the number of 4-foot by 8-foot sheets of 23/32 T&G OSB sheathing that are needed to construct the floor system.
