Mr. Newman also teaches a class on architecture. How could he explain how students will know when to find surface area and when to find volume? Give examples of key words that help students determine what a problem may be asking.

Answer: Surface area is used when the measurement of the outside of a figure is needed. Volume is used when the measurement for the inside of the figure is needed. Key words for volume include fill and space. Key words for surface area include outside and cover.

Your welcome :)

When teaching students how to differentiate between finding surface area and volume in architecture problems, Mr. Newman can provide them with some guidelines and key words to help them identify the specific type of calculation required. Here's how he could explain it:

"Alright, class, let's discuss how we can determine whether we need to find the surface area or volume in a given architecture problem. Understanding this distinction is crucial, as it will help us choose the appropriate formulas and calculations for each situation.

Firstly, let's talk about surface area. Surface area refers to the total area of all the exposed or outer surfaces of a three-dimensional object. It helps us understand how much material would be needed to cover or enclose an object. So, when you encounter these types of keywords or phrases in a problem, it usually indicates that you need to find the surface area:

  • 1. Covering: If the problem involves covering an object with paint, wallpaper, or any other material, it's a strong hint that you're looking for surface area. For example, "How much wallpaper is required to cover the walls of a room?"

  • 2. Wrapping or packaging: If the problem mentions wrapping a gift, packaging an item, or determining the material needed for a container, it likely involves surface area. For instance, "What is the surface area of a cylindrical container used for storing spices?"

  • 3. Exposed surfaces: If the problem focuses on calculating the area of exposed sides or faces of an object, such as finding the area of a façade or the outside walls of a building, you're dealing with surface area. For example, "What is the total surface area of a rectangular building?"

Now, let's move on to volume. Volume refers to the amount of space occupied by a three-dimensional object. It helps us understand how much material an object can hold or how much space it takes up. Here are some keywords or phrases that can indicate a volume calculation:

  • 1. Capacity or volume: If the problem involves determining the amount of liquid or substance an object can hold, such as finding the volume of a water tank or the capacity of a storage container, you're likely working with volume. For instance, "What is the volume of a cylindrical tank?"

  • 2. Filling or filling up: If the problem mentions filling a container with a specific substance, like sand, water, or concrete, it generally involves volume. For example, "How much concrete is needed to fill a rectangular foundation?"

  • 3. Inner space: If the problem focuses on calculating the space inside an object, such as finding the volume of a room or a storage compartment, you're dealing with volume. For instance, "What is the volume of a rectangular storage box?"

Remember, these keywords and phrases are not exhaustive, but they provide valuable clues about whether you should be looking for surface area or volume in an architecture problem. By paying attention to these indicators, you'll be able to apply the appropriate formulas and solve the problems accurately. Practice identifying these cues, and soon you'll be able to navigate architecture calculations with ease!"

Mr. Newman could reinforce these explanations with visual examples and practice problems to further solidify students' understanding of when to find surface area and when to find volume in architecture.
