For a regular prism (where all the sides are the same) calculate the area of one of the sides and multiply by the total number of sides. For irregular prisms (with different sides) calculate the area of each side. Add your two answers together (ends × sides) to find the total surface area of the prism.

The Curved surface area of cuboid is the sum of the areas of its six faces. The surface area is the total area of all the faces of a 3D shape. CSA of a cuboid is calculated using the given Curved Surface Area (CSA) Of Cuboid Formula. First add both length and breadth, then multiply by 2 with Height.

To calculate the surface area of a cylinder using a net, you need to figure out the area of the two circles and the area of the rectangle. First, to find the area of a circle, use the following formula. There are two circular bases in the cylinder, so multiply the area of the circle by two for the sum of the two areas.

Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

The basic formula for the surface area of any pyramid, regular or irregular, is Total Surface Area = Base Area + Lateral Area. Don't confuse “slant height” with “height.” The “slant height” is the diagonal distance from the apex of the pyramid to the edge of the base.
