To determine the correct amount of concrete bags needed to lay a footing for a house, the first step is to calculate the volume of the footing in cubic yards. The necessary dimensions of the footing should typically include its width, depth, and length.

Given that 45 bags of concrete are needed for one cubic yard, the total number of bags can be calculated by first determining the total volume required and then multiplying that volume by 45. If the resulting calculation doesn't match any of the available choices for bags of concrete, the option that states "None of the above" becomes the solution.

In this scenario, if the available dimensions of the footing, when calculated, yield a requirement that does not correspond with the individual choices provided, that means none of those options accurately reflect the necessity based on the specific dimensions given. This reinforces why selecting the option indicating "None of the above" is appropriate. Therefore, without specific dimensions to confirm the calculations, this choice correctly addresses the question based on the information at hand.
