Which calculation would be needed to find each of the following?(4 points)

Question

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
