Lateral Surface area
The lateral surface area of a cuboid is 2h(l+b), i.e. ,2 x height x sum of length and breadth
Surface area
The surface area of a cuboid is 2(lb+bh+hl) , i.e. , 2 x (length x breadth + breadth x height +
height x length)
A cube is a three-dimensional solid object bounded by
six square faces, facets or sides, with three meeting at each vertex. The cube
can also be called a regular hexahedron and is one of the
five Platonic solids.
Lateral Surface area
The lateral surface area of cube is 4a2
Surface areaThe surface area of cube is 6a2
A cylinder is one of the most basic curvilinear geometric shapes, the surface formed by the
points at a fixed distance from a given line segment, the axis of the cylinder. The solid enclosed by this surface and by two planes
perpendicular to the axis is also called a cylinder.
Lateral surface area
The lateral surface area of cylinder is 2πrh
Surface areaThe surface area of cylinder is 2πr(r+h)
A cone is a 3-dimensional geometric shape that tapers smoothly from a base (usually flat and circular) to a point called the apex or vertex.
In common usage in elementary geometry, cones are assumed to
be right circular, where right means that the axis passes through the centre of the base
(suitably defined) at right angles to its plane, and circular means that the base is
a circle.
Lateral surface area
Lateral surface area of cone is πrl
Surface area Surface area of cone is πr(l+r)
A sphere is a perfectly round geometrical object in three-dimensional space, such as the shape of a round ball. Like a circle, which is in two
dimensions, a sphere is the set of points which are all the same distance r from a given point in space. This distance r is known as the radius of
the sphere, and the given point is known as the center of the sphere. The maximum
straight distance through the sphere is known as the diameter. It passes through the center
and is thus twice the radius.
A sphere is divided into two equal "hemispheres" by any plane that passes through its center. If
two intersecting planes pass through its center, then they will subdivide the sphere into four lunesor bi-angles, the vertices of which all coincide with the antipodal points lying on the
line of intersection of the planes.
Curved surface area
The curved surface area of Hemisphere is 2πr2
Surface area The total surface area of hemisphere is 3πr2
