To calculate the amount of wrapping paper needed to wrap the toy, we need to calculate the surface area of the triangular prism.
The formula for the surface area of a triangular prism is:
Surface area = (2 * base * height) + (base * perimeter of the triangle)
First, let's calculate the perimeter of the triangular base:
Perimeter = 27.9 + 28.4 + 5.1
Perimeter = 61.4
Now, we can calculate the surface area:
Surface area = (2 * 27.9 * 5.1) + (27.9 * 61.4)
Surface area = (56.58) + (1705.26)
Surface area = 1761.84
So, approximately 1762 square units of wrapping paper are needed to wrap the toy.
A toy came in a container that is shaped like a triangular prism. How much wrapping paper is needed to wrap the toy? Round your answer to the nearest whole number.
length is 30.5
sides are 27.9 28.4 5.1
height is 5.1
base is 27.9
