A community hall is in the shape of a cuboid.
The hall is 40m long, 15m wide and 3m high.
The community hall needs re-decorating with new paint for the walls and ceiling, and new tiles on the floor
A 10 litre of paint covers 25m^2 and costs £10.
1m^2 floor tiles cost £3 each.
Work out the total cost of paints and tiles needed to re-docorate the community hall.
Answers
Answer:
Step-by-step explanation:
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.
\text{Area of walls and ceiling}=(2*40*15)+(2*3*15)+(40*3)
\text{Area of walls and ceiling}=1200+90+120
\text{Area of walls and ceiling}=1410
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,
\text{ The total painting cost}=10*(\frac{1410}{25})
\text{ The total painting cost}=10*56.4=564
Therefore, the total painting cost is $564.
Tiles will be required for floor. Let us find the area of floor.
\text{Area of floor} = 40*3\text{ square meters}
\text{Area of floor} =120\text{ square meters}
Given: 1m squared floor tiles costs $3. So,
\text{Total cost for tiles} = 3*120 = 360
Therefore, the total cost for tiles is $360.
Now let us find combined total cost of tiles and paint.
\text{Combined total cost}= 564+360 = 924
Therefore, the combined total cost of tiles and paint is $924.

Answer:924
Explanation
Given-Length , Breadth and Height
We have been given that a community hall is in the shape of a cuboid.
Step1
The paint will be required for 4 walls and ceiling.
Let us find area of walls and ceiling.
Area of walls and ceiling=(2*40*15)+(2*3*15)+(40*3)
=1200+90+120
=1410
So, the area of walls and ceiling is 1410 square meters.
Step2.
Given: Cost for 10 liter of paint is 10 euro and 10 litre paint covers 25 m^2,
The total painting cost=10*(\frac{1410}{25})
=10*56.4=564
Total painting cost=564 Euro
Tiles will be required for floor. Let us find the area of floor.
Area of floor = 40*3\text{ square meters}
Area of floor =120\text{ square meters}
1m squared floor tiles costs 3euro. So,
Total cost for tiles = 3*120 = 360
he total cost for tiles is 360 euro
Now let to find combined total cost of tiles and paint.
Combined total cost= 564+360 = 924
so, the total combined cost of tiles and paint is 924.euro
