WebJan 26, 2024 · Surface Area of Cuboid: A cuboid is a three-dimensional (3D) geometrical object which consists of 6 rectangular faces. All angles of a cuboid are right angles and faces opposite to each other are equal. The surface area is defined as the area of faces of a closed surface. A cuboid is a 3D shape with 6 faces where each face resembles a … WebExample 1: surface area of a cuboid. Work out the surface area of the cuboid. Work out the area of each face. The area of the bottom is 9\times3=27cm^2 9 × 3 = 27cm2. The top face is the same as the bottom face so the area of the top is also 27cm^2 27cm2. The area of the front is 9\times4=36cm^2 9 × 4 = 36cm2.

WebThe surface area of a solid object is a measure of the total area that the surface of the object occupies. The mathematical definition of surface area in the presence of curved surfaces is considerably more involved than the definition of arc length of one-dimensional curves, or of the surface area for polyhedra (i.e., objects with flat polygonal faces), for … WebThe Total Surface Area of a Cuboid is the sum of all the 6 faces. So, we have to add all these areas to calculate the final Surface Area.
