To find the total amount of wrapping paper needed, we need to calculate the surface area of the rectangle or prism formed by the container.
The surface area of a rectangular prism is given by the formula:
Surface Area = 2lw + 2lh + 2wh
Plugging in the given dimensions:
Surface Area = 2(27.9)(30.5) + 2(27.9)(5.1) + 2(30.5)(5.1)
Surface Area = 1701 + 285.39 + 310.05
Surface Area = 2296.44
Therefore, approximately 2296 cm² of wrapping paper would be needed to wrap the toy in the container.
