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. (1 point) S.A. = cm2
To find the surface area of a triangular prism, we need to calculate the area of the two triangular faces and the three rectangular faces.
Let's denote the dimensions of the triangular prism as follows:
Base of the triangle = b
Height of the triangle = h
Length of the prism = l
The surface area of a triangular prism is given by the formula:
S.A. = 2 * (Area of triangle) + 3 * (Area of rectangle)
First, calculate the area of the triangular faces:
Area of triangle = (1/2) * b * h
Now, let's calculate the area of the rectangular faces:
Area of rectangle = b * l
Plug the values for b, h, and l, and calculate the total surface area. Round your answer to the nearest whole number.
