Question

Select all of the situations in which the surface area would be useful to know. (Select all that apply.) Ordering tiles to replace the roof of a house.

Estimating how long it will take to clean the windows of a greenhouse.
Deciding whether leftover soup will fit in a container.
Estimating how long it will take to fill a swimming pool with a garden hose. Buying fabric to sew a couch cover.
Deciding whether one muffin pan is enough to bake a muffin recipe.

Answer 1

Surface area is crucial when ordering tiles for a roof, estimating the time to clean greenhouse windows, or buying fabric for a couch cover due to the need to measure coverage. It's less relevant when determining container capacity, filling a swimming pool, or baking muffins, where volume is key.

Step-by-step explanation:

The concept of surface area is mainly applied in situations that involve covering, painting, wrapping or decorating something. Therefore, knowing the surface area would be useful in the following situations:

• Ordering tiles to replace the roof of a house - you need to know the surface area of the roof to decide how many tiles you need.
• Estimating how long it will take to clean the windows of a greenhouse - the time taken to clean will depend on the surface area of the windows.
• Buying fabric to sew a couch cover - the amount of fabric needed is determined by the surface area of the couch.

On the other hand, deciding whether leftover soup will fit in a container, estimating how long it will take to fill a swimming pool with a garden hose, or deciding whether one muffin pan is enough to bake a muffin recipe are situations where volume, not surface area, is relevant.

Answer 2

Correct Answers:

1) Ordering tiles to replace the roof of a house.

Tiles of a roof cover the top side of a three dimensional house

2) Estimating how long it will take to clean the windows of a greenhouse.

To find this you would divide the surface area of the windows by the rate someone could clean them, giving you a time

3) Buying fabric to sew a couch cover.

Similar to the roof, you are covering a portion of one side of a 3-dimentional object

Incorrect Answers:

1) Deciding whether leftover soup will fit in a container.

Liquid containers are measured in volume

2) Estimating how long it will take to fill a swimming pool with a garden hose.

Liquid containers are measured in volume

3) Deciding whether one muffin pan is enough to bake a muffin recipe.

Muffin batter is liquid, and the size/volume of muffins vary
