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.
