A cuboid is a region covered by its six rectangular faces. The surface area of a cuboid is equal to the sum of the areas of its six rectangular faces.

**Surface Area of the Cuboid**

Consider a cuboid whose dimensions are l × b × h, respectively.

The total surface area of the cuboid (TSA) = Sum of the areas of all its six faces

TSA (cuboid) = 2(l × b) + 2(b × h) + 2(l × h) = 2(lb + bh + lh

Lateral surface area (LSA) is the area of all the sides apart from the top and bottom faces.

The lateral surface area of the cuboid = Area of face AEHD + Area of face BFGC + Area of face ABFE + Area of face DHGC

LSA (cuboid) = 2(b × h) + 2(l × h) = 2h(l + b)

Length of diagonal of a cuboid =√(l2 + b2 + h2)

**Volume of a Cuboid**

The volume of a cuboid is the space occupied within its six rectangular faces.

Volume of a cuboid = (base area) × height = (lb)h = lbh

**Surface Area and Volume of Cube**

A cube is a three-dimensional solid that has six square faces, twelve edges and eight vertices.

**Surface Area of Cube**

As we know, one of the important properties of a cube is length = breadth = height.

If we assume that the length of the cube is “l”, and hence we get

l = breadth = height

So, obviously, here we get,

Breadth = l

Height = l

The total surface area of the cube (TSA) = Sum of the areas of all its six faces.

In case of all faces has an equal area, TSA of Cube = 6 × area of Square = 6l^{2} square units.

Similarly, the Lateral surface area of cube = 2(l × l + l × l) = 4l2

Note: Diagonal of a cube =√3l

**Volume of a Cube**

Volume of a cube = base area × height

Since all dimensions of a cube are identical, volume = l3

Where *l* is the length of the edge of the cube.

**Surface Area and Volume of Cylinder**

A cylinder is a solid shape that has two circular bases connected with each other through a lateral surface. Thus, there are three faces, two circular and one lateral, of a cylinder. Based on these dimensions, we can find the surface area and volume of a cylinder.

**Surface Area of Cylinder**

Take a cylinder of base radius *r* and height *h* units. The curved surface of this cylinder, if opened along the diameter (*d* = 2*r*) of the circular base can be transformed into a rectangle of length 2πr and height *h* units. Thus,

CSA of a cylinder of base radius *r* and height h = 2π × r × h

TSA of a cylinder of base radius *r* and height h = 2π × r × h + area of two circular bases

=2π × r × h + 2πr2

=2πr(h + r)

### Volume of a Cylinder

Volume of a cylinder = Base area × height = (πr2) × h = πr2h

**Volume of a Right Circular Cone**

The volume of a Right circular cone is 1/3 times that of a cylinder of the same height and base.

In other words, 3 cones make a cylinder of the same height and base.

The volume of a Right circular cone =(1/3)πr2h

Where ‘*r’* is the radius of the base and ‘*h’* is the height of the cone.
