Answer:
Total cost for tiles and paints is $924.
Step-by-step explanation:
We have been given that a community hall is in the shape of a cuboid. The hall is 40m long 15m high and 3m wide.
The paint will be required for 4 walls and ceiling.
Let us find area of walls and ceiling.
[tex]\text{Area of walls and ceiling}=(2*40*15)+(2*3*15)+(40*3)[/tex]
[tex]\text{Area of walls and ceiling}=1200+90+120[/tex]
[tex]\text{Area of walls and ceiling}=1410[/tex]
Therefore, the area of walls and ceiling is 1410 square meters.
Given: Cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. Therefore,
[tex]\text{ The total painting cost}=10*(\frac{1410}{25})[/tex]
[tex]\text{ The total painting cost}=10*56.4=564[/tex]
Therefore, the total painting cost is $564.
Tiles will be required for floor. Let us find the area of floor.
[tex]\text{Area of floor} = 40*3\text{ square meters}[/tex]
[tex]\text{Area of floor} =120\text{ square meters}[/tex]
Given: 1m squared floor tiles costs $3. So,
[tex]\text{Total cost for tiles} = 3*120 = 360[/tex]
Therefore, the total tiles cost is $360.
Now let us find combined total cost of tiles and paint.
[tex]\text{Combined total cost}= 564+360 = 924[/tex]
Therefore, the combined total cost of tiles and paint is $924.
