Variables
Variable | Meaning |
---|---|
BT | Baseboard Trim (the total length of trim needed) |
L | Length of the room |
W | Width of the room |
How to Calculate ?
Firstly, measure the length (L) and width (W) of the room where the baseboard trim will be installed. Secondly, add the length and width together. Finally, multiply this sum by 2 to calculate the total length of baseboard trim (BT) needed to cover all four walls of the room
Solved Examples:
Example 1:
Given:
- Length of the room (L) = 12 feet
- Width of the room (W) = 10 feet
Calculation | Instructions |
---|---|
Step 1: BT = | Start with the formula. |
Step 2: BT = | Replace L with 12 feet and W with 10 feet. |
Step 3: BT = | Add the length and width: |
Step 4: BT = 44 feet | Multiply 22 by 2 to get the total baseboard trim needed. |
Answer:
The total length of baseboard trim needed is 44 feet.
Example 2:
Given:
- Length of the room (L) = 15 feet
- Width of the room (W) = 8 feet
Calculation | Instructions |
---|---|
Step 1: BT = | Start with the formula. |
Step 2: BT = | Replace L with 15 feet and W with 8 feet. |
Step 3: BT = | Add the length and width: |
Step 4: BT = 46 feet | Multiply 23 by 2 to get the total baseboard trim needed. |
Answer:
The total length of baseboard trim needed is 46 feet.
Baseboard Trimming; Things You Must Know
The Baseboard trimming is a a decorative purpose element which is set up along the edges of interior walls. It is also known as baseboard modelling.
Apart from giving an aesthetic look, it also protects the walls from foot damages, from vacuum cleaners and furniture. It covers up the gaps where wall meets the floor, giving a neat and clean look.
