Question

Which calculation would be needed to find each of the following?(4 points)
Volume | Surface area
the amount a cereal box can hold
The amount of paint needed to paint the sides of a house
the amount of wrapping paper needed to wrap a gift
the amount of water a bottle can hold

Answer 1

To determine the necessary calculations for each scenario, let's break down the requirements:

1. **Volume | Surface Area**
- **The amount a cereal box can hold**:
- **Calculation**: Volume
- **Formula**: Volume = length × width × height (for a rectangular box)

2. **The amount of paint needed to paint the sides of a house**:
- **Calculation**: Surface Area
- **Formula**: Surface Area = Sum of the areas of all the walls (for a rectangular house, it would be 2(length × height) + 2(width × height))

3. **The amount of wrapping paper needed to wrap a gift**:
- **Calculation**: Surface Area
- **Formula**: Surface Area = 2(length × width + length × height + width × height) (for a rectangular box shape)

4. **The amount of water a bottle can hold**:
- **Calculation**: Volume
- **Formula**: Volume = (depending on the shape of the bottle); for a cylindrical bottle, Volume = πr²h (where r is the radius and h is the height)

In summary:
- Cereal box: **Volume**
- Paint for house: **Surface Area**
- Wrapping paper: **Surface Area**
- Water bottle: **Volume**
