A door that is 15 inches wide 25 inches high and 2 inches thick is to be decoratively wrapped in gift paper how many square inches of give paper are needed
as always with such prisms,
A = 2(15*25 + 15*2 + 25*2) = ____
But that will not allow any overlap to allow taping the edges. Works for a coat of paint; not so much for paper.

To calculate the amount of gift paper needed to wrap the door, we need to find the total surface area of the door.
The door has a dimension of 15 inches wide and 25 inches high. Since it is 2 inches thick, we need to consider both sides of the door for wrapping.
First, let's calculate the area of each side of the door:
- One side has a width of 15 inches and a height of 25 inches, so the area is 15 inches x 25 inches = 375 square inches.
- Since the door is 2 inches thick, it has a second side with the same dimensions. So we have another area of 375 square inches.
To find the total surface area, we need to consider both the front and back of the door, as well as the top and bottom:
- The front and back are the two sides with areas of 375 square inches each, so their total area is 375 square inches + 375 square inches = 750 square inches.
- The top and bottom of the door have the same dimensions as the width and thickness, so each has an area of 15 inches x 2 inches = 30 square inches. Since there are two sides, their total area is 30 square inches + 30 square inches = 60 square inches.
Adding all the areas together, we get the total surface area of the door:
750 square inches (front and back) + 60 square inches (top and bottom) = 810 square inches.
Therefore, you would need 810 square inches of gift paper to wrap the door decoratively.
To find the total square inches of gift paper needed to wrap the door, we need to calculate the surface area of the door.
The door has two sides with dimensions 15 inches wide and 25 inches high, so each side will have an area of 15 inches * 25 inches = 375 square inches.
The door also has two other sides with dimensions 25 inches high and 2 inches thick. Each of these sides has an area of 25 inches * 2 inches = 50 square inches.
Finally, the door has two more sides with dimensions 15 inches wide and 2 inches thick. Again, each of these sides has an area of 15 inches * 2 inches = 30 square inches.
Now, we can calculate the total surface area of the door by adding up the areas of all six sides: 2 * 375 square inches + 2 * 50 square inches + 2 * 30 square inches = 750 square inches + 100 square inches + 60 square inches = 910 square inches.
Therefore, you will need 910 square inches of gift paper to wrap the door decoratively.
