A tea bag is shaped like a square pyramid with the base measuring 4 centimeters on each side. The dlant height is 4.5 centimeters. How much mesh is used to create the tea nag?

A square pyramid is a pyramid that has a square as its base. Thus, its sides are composed of 4 triangles.

We need to get the area of the square and the triangles to get the total surface area.

Square sides = 4 cm.

triangle: base = 4cm; height = 4.5

Area of the square = s² = (4cm) ² = 16 cm²

Area of the triangle = hb/2 = 4.5cm (4cm) / 2 = 9 cm²

9 cm² x 4 triangles = 36 cm²

Total area = 16cm² + 36cm² = 52 cm² is the area of the required mesh to create the tea bag.
