A cylinder is a three-dimensional solid that holds two parallel bases joined by a curved surface at a fixed distance.

The total surface area of a cylinder is the sum of the curved surface area and the area of two circular bases. as \$"A" = 2πr^2 + 2πr"h"\$, where r is the radius, and h is the height.

The first part of the formula \$2πr^2\$ represents the area of the two circular bases, while the second part \$2πr"h"\$ represents the area of the lateral curved surface.

A cone is a three-dimensional geometric figure with a circular base and a curved surface that extends to a single point called the apex.

The base of the cone is a circle, and its area is calculated using the formula for the area of a circle: A = \$πr^2\$.

The lateral surface area of a cone is the area of the curved surface excluding the base. It is calculated using the formula: A = \$πrl\$, where r is the radius and l is the slant length.

Therefore, the complete formula for the surface area of a cone is: SA = \$πr^2 + πrl\$

A cube is a three-dimensional shape with six square faces.

It has eight vertices, twelve edges, and six faces, with all edges being equal.

The surface area (SA) of a cube is calculated by adding up the areas of all six faces. Since all the faces are identical squares, we can use the formula SA = \$6s^2\$, where s is the side length of one side of the cube.

A cuboid, also known as a rectangular prism, has 8 vertices, 12 edges, and 6 faces, all rectangular and have angles measuring 90 degrees.

A cuboid’s surface area (SA) is found by summing the areas of all six faces.

This is expressed by the formula SA=2lw+2lh+2wh, where l, w, and h represent the cuboid’s length, width, and height.
