This poster presents a clear and friendly overview of the surface area formulas for common 3D shapes. Designed to look like a teacher’s handwritten notes, it uses simple sketches, neat labels, and soft colors to make learning easy and engaging. Each shape—cube, cuboid, cylinder, cone, sphere, and triangular prism—is illustrated with labeled dimensions and its corresponding surface area formula. The layout is clean and organized, with sections separated for easy reading. Playful touches like smil
