Question 1149923: Can someone please explain the problem
If a room has a width of 5 m, a length of 6 m, and a height of 5 m. How many tiles do you need to decorate your room if each tile is 6 cm in length and width? Note that the ceiling and floor do not need the tiles. If each tile cost $0.5, how much money will you need to spend on decorating your room?

Since the size of the tile is in centimeters, change the dimensions of the room to cm so that the units are consistent.

You then have two walls each 500x500cm and two walls 600x500cm. The total area to be covered in square centimeters is

500%2A500%2B600%2A500+=+250000%2B300000+=+550000

The area of each tile is 6*6 = 36 square centimeters. The number of tiles required is

550000%2F36

You can do the calculation and then use the result to find the cost of the tiles at $0.50 each.

Note that 6-cm tiles will not exactly cover any of the walls, so some tiles will need to be cut. Furthermore, the mathematical calculations do not take into consideration the spacing between the tiles.

So in a real world case, the mathematical calculations will only give a good estimate of the total number of tiles and the total cost.
