Surface area of 3D solids (prisms, cylinders, cones, pyramids, spheres)

What you'll learn

1. Calculate the surface area of rectangular prisms by summing the areas of all faces
2. Calculate the surface area of cylinders using SA = 2*pi*r^2 + 2*pi*r*h
3. Calculate the surface area of pyramids using SA = B + (1/2)*P*l
4. Calculate the surface area of cones using SA = pi*r^2 + pi*r*l
5. Calculate the surface area of spheres using SA = 4*pi*r^2
6. Solve real-world problems requiring surface area calculations (packaging, painting, material costs)

Prerequisites

• Area of common 2D shapes and composite figures
• Circumference and area of circles
