Answer 1

Which calculation would be needed to find each of the
following? (4 points)
 The amount of cereal 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
which one goes to volume and which one goes to surface area

Answer 2

To determine the quantities needed for each of the scenarios you provided, you would use the following calculations:

1. **The amount of cereal a cereal box can hold:**
- **Calculation:** Volume of the box.
- **Formula:** Volume = length × width × height (for a rectangular box). If the box has a different shape, use the appropriate volume formula corresponding to that shape.

2. **The amount of paint needed to paint the sides of a house:**
- **Calculation:** Surface area of the walls.
- **Formula:** Surface Area = (perimeter × height) for the walls, plus any additional calculations for windows and doors. The total surface area is then multiplied by the coverage area per unit of paint to determine the amount of paint needed.

3. **The amount of wrapping paper needed to wrap a gift:**
- **Calculation:** Surface area of the gift.
- **Formula:** Surface Area = 2(lw + lh + wh) for a rectangular prism (box). This includes all sides. You can also adjust for any irregular shapes accordingly.

4. **The amount of water a bottle can hold:**
- **Calculation:** Volume of the bottle.
- **Formula:** Volume = πr²h for a cylindrical bottle, where r is the radius and h is the height. Use the appropriate volume formula for different shapes (e.g., spherical, cubical, etc.).

In each case, the calculations involve determining the volume or surface area, which helps in assessing capacity or coverage.
