🛎️ What is Surface Area?
- Surface area is the total area of all the faces of a solid.
- To find it, calculate the area of each face and add them together.
🛎️ Surface Area of Cubes and Cuboids
- A cuboid has 6 faces, arranged in 3 identical pairs.
- A cube has 6 identical square faces.
🛎️ Calculating the Surface Area of a Cuboid
- A cuboid has 3 pairs of identical faces: top and bottom, front and back, and left and right.
- Find the area of one face in each pair, multiply each by 2, then add them together.
🛎️ Calculating the Surface Area of a Cuboid
- A prism has two identical ends and several rectangular side faces.
- Find the area of every face, then add them all together to get the surface area.
