4. A rectangulat solid box measures 2.75 feet by 4.05 feet by 480 inches. In cubic yards, what is the volume of the box? Express your answer as a decimal to the nearest tenth.

5. In the diagram, trangle ABC is inscribed in the circle and AC=AB. The measure of angle BAC is 42 degrees and segment ED is tangent to the circle at point C. What is the measure of angle ACD?

4) Convert all those measurements to yard and multiple them.
1 foot = 1/3 yard
1 inch = 0.027778

So 0.916 * 1.35 * 13.333 = 16.5 yd^3

5) After a quick glance, I believe it's 55.5 degree.
