Rectangular Prism - Definition with Examples
What is a Rectangular Prism?
Rectangular Prism Definition: A rectangular prism is a 3-dimensional solid shape with 4 rectangular sides joined together at the edges, and forming two pairs of rectangular bases parallel to each other.
Types of Rectangular Prisms
Rectangular prisms are of two types:
Right Rectangular Prism: A rectangular prism whose sides are at right angles to the bases are known as right rectangular prism.
Non-Right Rectangular Prism: A rectangular prism whose sides are not at right angles to the bases are known as non-right rectangular prism.
Rectangular Prism and its Net
The net of the rectangular prism consists of two identical rectangular bases and 4 rectangular sides.
Surface Area of a Rectangular Prism
Area of the orange face = 2 (width × length) = 2wl
Area of the blue face = 2 (length × height) = 2lh
Area of the green face = 2 (width × height) = 2wh
Surface area = Sum of all the area of its faces = 2wl + 2lh + 2wh = 2 (wl + lh + wh)
|Surface area = 2 ( wl + il + wh )|
Volume of a rectangular prism
Volume of a rectangular prism is simply obtained by multiplying all three dimensions. i.e. length (l), height (h) and width (w).
|Volume = l X W X h = lwh|
