A you came in a container that is shaped like a triangular prison how much wrapping paper is needed to wrap the toy? Round answer to the nearest whole number
To calculate the amount of wrapping paper needed to wrap a toy in a triangular container, we need to find the surface area of the triangular prism.
The surface area of a triangular prism is given by the formula:
Surface Area = 2 * base area of the triangle + perimeter of the triangle * height of the prism.
Let's assume the toy is a regular triangular prism with sides of 4 inches, and a height of 6 inches.
First, calculate the base area of the triangle:
Base Area = (1/2) * base * height
Base Area = (1/2) * 4 * 6
Base Area = 12 square inches
Next, calculate the perimeter of the triangle:
Perimeter = sum of all three sides
Perimeter = 4 + 4 + 4
Perimeter = 12 inches
Now, calculate the surface area of the triangular prism:
Surface Area = 2 * 12 + 12 * 6
Surface Area = 24 + 72
Surface Area = 96 square inches
Therefore, approximately 96 square inches of wrapping paper is needed to wrap the toy.
The dimensions are 5.1cm 27.9cm 28.4cm and 30.5 cm
To calculate the amount of wrapping paper needed to wrap the toy in a triangular container with dimensions 5.1cm, 27.9cm, 28.4cm, and 30.5cm, we will follow the same steps as before.
Calculating the base area of the triangle:
Base Area = (1/2) * base * height
Base Area = (1/2) * 27.9 * 28.4
Base Area = 397.62 square cm
Calculating the perimeter of the triangle:
Perimeter = sum of all three sides
Perimeter = 27.9 + 28.4 + 30.5
Perimeter = 86.8 cm
Calculating the surface area of the triangular prism:
Surface Area = 2 * 397.62 + 86.8 * 5.1
Surface Area = 795.24 + 442.68
Surface Area = 1237.92 square cm
Therefore, approximately 1238 square centimeters of wrapping paper is needed to wrap the toy.
