In fact he makes nylon tea bags. The bags are in the shape of a triangular pyramid how much neon is needed to make 50 tea bags given to the following dimensions
°base of the equilateral triangles: 40 mm
°height of the base triangle: 35 mm
°slant height of the equilateral triangular faces: 45 mm
3,062.5 mm
153,125 mm
3,400 mm
170,000 mm
To find the surface area of one triangular pyramid tea bag, we need to calculate the base area and the lateral area.
Base area of equilateral triangle = (sqrt(3)/4)*(side length)^2
Base area = (sqrt(3)/4)*(40 mm)^2 = 692.82 mm^2
Lateral area of one face = (1/2)*perimeter*slant height
Lateral area = (1/2)*((3*40 mm)*45 mm) = 1,350 mm^2
Total area of one tea bag = 3*(base area) + 3*(lateral area) = 4,423.46 mm^2
Total area for 50 tea bags = 50 * 4,423.46 mm^2 = 221,173 mm^2
Therefore, the correct answer is approximately 221,173 mm.
