Area, volume, and surface area

The topic  appears under the 7th Grade Math Mission. This exercise practices the relationship between area and volume with three-dimensional figures.

Types of Problems
There are two types of problems in this exercise:


 * 1) Use area formulas to solve the problem: This problem provides a real-life scenario involving area or surface area formulas. The student is asked to solve the problem and provide the solution in the text box.Avasa1.png
 * 2) Use volume formulas to solve: This problem provides a real-life scenario involving volume. The student is asked to find the solution to the word problem and write the answer in the space provided.Avasa2.png

Strategies
The concept of surface area and volume is more useful than the actual formulas on this exercise because the shapes used can be represented by nets.
 * 1) The surface area is the sum of the areas of each side.
 * 2) Be careful to read the problem to see if one object is made or several are made.
 * 3) The volume problem involving crates can be done mechanically by dividing the volume of the whole cargo ship by the volume of one of the crates.
