To calculate the amount of wrapping paper needed, you need to find the surface area of the package.
The surface area of a rectangular prism (the shape of the package) is found by adding the areas of all six sides.
The formula for the surface area of a rectangular prism is:
2lw + 2lh + 2wh
In this case, the dimensions are:
Length (l) = 15 in
Width (w) = 4 in
Height (h) = 7 in
Plugging these values into the formula:
Surface Area = 2(15)(4) + 2(15)(7) + 2(4)(7)
Surface Area = 30 + 210 + 56
Surface Area = 296 square inches
Therefore, 296 square inches of wrapping paper is needed for the package.
how much wrapping paper is needed for a package that is 4 in. wide 7. in high and 15. in long?

can you try again? maybe a lower or higher number
Of course! Let's try finding the amount of wrapping paper needed for a different package.
Let's say the package dimensions are:
Width (w) = 6 in
Height (h) = 10 in
Length (l) = 12 in
Using the same formula for the surface area of a rectangular prism:
Surface Area = 2lw + 2lh + 2wh
Plugging in the new dimensions:
Surface Area = 2(12)(6) + 2(12)(10) + 2(6)(10)
Surface Area = 144 + 240 + 120
Surface Area = 504 square inches
Therefore, 504 square inches of wrapping paper is needed for this package.

Therefore, 504 square inches of wrapping paper is needed for this package.
