Describe how units can help to check the answers and solve problems. Give examples.
Consider a box with the side lengths in inches. The volume of the box would be calculated in cubic inches. The key word "cube or cubic" in this context means that the unit inches is raised to the third power. The mathematical symbol to represent the unit of the volume of the box is "in ^3."

Consider the following exam question and student solution. Determine whether the solution is correct. If it is not correct, write a note to the student explaining why it is wrong and give a correct solution. Exam question: You can buy a 34-pound bag of flour for $66 or you can buy a 1-pound bag for $0.39. Compare the per pound cost for the large and small bags. Student solution: The large bag price is 34÷$6=$5.67 per pound, which is much more than the39¢ per pound price of the small bag.
The student's solution is incorrect. The student's division gives an answer with units of pounds per dollar, but he should seek an answer in dollars per pound. The answer in dollars per pound is $. 18 per pound, which is less than the $0.39 per pound for the smaller bag. (Round to the nearest cent as needed.)

Units are words that describe what is being measured or counted.
Complete parts (a) through (c) below. a. A warehouse is 65 yards long, 32 yards wide, and 7 yards high. What is the area of the warehouse floor? If the warehouse is filled to half its height with tightly packed boxes, what is the volume of the boxes? b. A room has a rectangular floor that measures 27 feet by 13 feet and a flat 8-foot ceiling. What is the area of the floor and how much air does the room hold? c. A grain silo has a circular base with an area of 155 square feet and is 23 feet tall. What is the total volume?
a) The area of the warehouse floor is 2080yd2. (Type an integer or a decimal.) The volume of the boxes in the warehouse is 7280^2yd cubed . b. The area of the floor is 351^2 ft squared . The amount of air the room can hold is 2808ft^3 cubed . c. The volume of the grain silo is 3565^3ft cubed .
