The surface area of the composite figure is approximately 234.5 square centimeters.
What is the surface area of the composite figure?
In this question we have a composite figure formed by a pyramid and a right prism, both with the same square base, of which we must determine its surface area, constituted by the sum of the areas of the four triangles, the area of the square base and the areas of the four rectangles:
A = (6 cm)² + 4 · (6 cm) · (4 cm) + 4 · 0.5 · √[(8 cm)² + (3 cm)²] · (6 cm)
A ≈ 234.5 cm²
