A. Your parents decided to enlist your help in installing hardwood floors into your house. First you install a plywood subfloor that is 1/2 inch thick to help reduce squeaking once the hardwood is installed. The hardwood flooring your parent's chose is 3/4 inch thick. To install the hardwood planks on top of the plywood you will use a flooring nailer that shoots the nails at a 45 angle. 1. Draw a diagram to illustrate the situation. Label it with all the pertinent measurements. 2. Determine the exact length of nail that will go completely through the hardwood planks and the plywood subfloor. Include ALL calculations. Round the final answer to the nearest thousandths. 3. The nails that the floor nailer uses are called L-shaped cleats and they come in standard sizes. The options are 1.5 in, 1.75 in and 2 in. Which length should you buy? Why
