What are some similarities and differences between a situation that involves calculating surface area and a situation that involves calculating volume.

Answer: Surface area is how much area of the object is exposed to the outside. The volume is how much space is inside the shape. The surface-area-to-volume ratio tells you how much surface area there is per unit of volume ... If you are given the numbers, then you simply divide the surface area number by the volume number

The surface area is the size of a 2-dimensional surface of a 3-dimensional object. The unit of measure will be a square unit, such as square inches or square meters or square miles. The volume of an object is the total amount of space contained inside the object, and it is 3-dimensional, so the unit of measure is a cube, or 3-dimensional unit, cubic inches, cubic meters, cubic miles.

Speaking of cubes, think of a cube 1 inch on each side. (This is kind of like a large die, as in one of two dice, only without the dots.) Each edge is 1 inch long. Each face is one square inch in area. It has 6 faces, just like a die, top, bottom, and 4 sides. So the surface area of a 1-inch cube is 6 square inches. The volume of a 1-inch cube is calculated by multiplying length x width x height: 1 inch x 1 inch x 1 inch = 1 cubic inch.
