A wedge of cheese is shaped like a triangular prism.
How much plastic wrap is needed to cover the wedge
of cheese?
(1 point)
287 cm2
330 cm2
810 cm2
240 cm2
To calculate the amount of plastic wrap needed to cover the wedge of cheese, we need to determine the total surface area of the cheese.
First, find the area of the triangular base of the prism. The formula for the area of a triangle is (1/2) x base x height.
Let's assume the base of the triangle is 10 cm and the height is 8 cm (these are just hypothetical measurements for illustration purposes).
Area of triangle = (1/2) x 10 cm x 8 cm = 40 cm2
Next, find the area of the three rectangular sides of the prism. The formula for the area of a rectangle is length x width. Let's assume the length of the triangle is 12 cm and the width is 5 cm (again, hypothetical measurements for illustration purposes).
Area of rectangle = 3 x (12 cm x 5 cm) = 3 x 60 cm2 = 180 cm2
Now, add the area of the base and sides together to get the total surface area of the wedge of cheese:
Total surface area = 40 cm2 (triangle base) + 180 cm2 (rectangular sides) = 220 cm2
Therefore, the correct answer is not listed above, but the total amount of plastic wrap needed to cover the wedge of cheese is 220 cm2.
