Find the area of a square in square inches whose side is 1.3 ft?
I keep getting this one wrong I would think that 1.3 feet is 16 inches and then multiply that by that by sixteen but that is not the correct answer.

One thing that can help when doing unit conversions is properly setting up your fractions. In this case, you need $ \frac{1.3\text{ ft}}{1}\times \frac{12\text{ in}}{1\text{ ft}} = 15.6\text{ in} $ Now it's clear from the fractions that you have to multiply 1.3 by 12 to convert feet to inches. The area of a square is $s^2$ where $s$ is the length of a side, so the area is $(15.6)^2=243.36$ square inches (don't forget the units).
