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.

S.A. = cm?
it is 30.5cm long
the triangle face is 5.1cm 28.4cm and 27.9cm
First, calculate the surface area of the triangular prism:
Surface area = 2 * base area + lateral area
Surface area = 2 * (1/2 * base * height) + (perimeter of base * height)
Surface area = (base * height) + (perimeter * height)
Surface area = (5.1 * 28.4) + (5.1 + 28.4 + 27.9) * 30.5
Surface area = (145.44) + (61.4) * 30.5
Surface area = 145.44 + 1871.7
Surface area = 2017.14
Now, to wrap the toy, you would need the surface area of the container. Therefore, you would need 2017 cm² of wrapping paper to wrap the toy.
