Part 1: What is the formula for the volume of a rectangular solid? Find an object in your residence that has the shape of a rectangular solid. Measure and record the length, width, and height of your object in either centimeters (to the nearest 10th of a centimeter) or inches (to the nearest quarter of an inch). Compute the volume of your solid and include units with your answer. You do not need to use fractions in your computations; their decimal equivalents are fine. Include the type of object, the measurements, and show how you obtained the volume. Please summarize your results in a brief sentence using the correct units of measure for volume.

Part 2: The equation C=mx+b can be used to model the monthly cost, C, of a cell phone plan where b is the flat monthly cost, m represents the cost in dollars per minute and x is the number of minutes used in the month. Choose a flat monthly rate and cost per minute and insert the values you have chosen for m and b into the equation. Then use this equation to find the total monthly cost, C, if 67 minutes are used (or as if there were 67 minutes of overage).

Be sure to reference your sources using APA style.
