__________ surface area of room = area of 4 walls.
Solution:
The area of four halls can be calculated with the help of the schematic diagram of a room below:
The area of four walls of the room as shown above are referred to as the lateral surface area of the room. The lateral surface area of the room does not include the roof and the floor.
✦ Try This: The total space of a room length L, breadth B and height H is calculated as the ___________ of the cuboid of the same measurements.
A room can be schematically represented by the diagram below.
A room with measurements of L, B and H can be thought of as a cuboid of length (L), Breadth(B) and height(H).
Therefore space occupied by a cuboid is basically termed as its volume = L × B × H
Similarly the space occupied by a room of length (L), breadth(B) and height (H) is the volume of the room which is = L × B × H
The total space of a room length L, breadth B and height H is calculated as the volume of the cuboid of the same measurements.
