Those values are r2 + r2 + 2rh 2r2 + 2rh. To compute the floor area of a room, CLICK HERE. The top, the bottom, and the walls of the cylinder (the lateral surface area) determine the total surface area.To compute the surface area of the interior walls and ceiling of a room, CLICK HERE.To compute the surface area of the interior walls of a room, CLICK HERE.

To compute the volume of a room, CLICK HERE.To compute the cost to paint or prime a room, CLICK HERE.To compute the number of gallons to paint or primer a room, CLICK HERE. Since a rectangular box or tank has opposite sides which are equal, we calculate each unique sides area, then add them up together, and finally multiply by two.To compute the area of the interior of the room without the floor.

A = Surface area of the interior of the room.

To compute the area of the interior of the room without the floor in the following equation:

The area of the floor, where Area = L*W (the same as the ceiling)įor the total surface area of the interior of a room including walls, ceiling and floor, use the following equation:.

The area of the ceiling, where Area = L*W.

Write the given figures: l 11cm, w 5cm, h 3cm. We’ll start by finding the surface area first. Recall that the area of a rectangle is the product of its length and width: A l w.

The area of other two walls, where Area = W*H The total surface area of a rectangular prism is the sum of all the areas of its six rectangular sides.

The area of two walls, where Area = L*H.

These areas can be determined by the dimensions of the room. The surface area of the interior of a room including the walls and ceiling is the sum of the area of the walls and the area of the ceiling. However, these can be automatically converted to other area units (e.g. (A) Total Surface Area (Walls, Ceiling and Floor).Total Surface Area (A): The calculator will returns: INSTRUCTIONS: Choose units and enter the following: If the height and width are in cm, the area is shown in cm². The Total Surface Area of a Room calculator computes the surface area of the interior of a rectangular room including the walls, ceiling and floor based on the length, width and height of the room. To work out the area of a square or rectangle, multiply its height by its width.
