A community hall is in the shape of a cuboid the hall is 40m long

2172 is the total cost

Cost for tiles: 1800

cost of paint: 372

Find the surface area of the wall without floor:(for cost of paint)

40 x 15 + 40x3x2 + 15x3x2 = 600 + 240 + 90 = 930

Cost: 930/25 x 10 = 372

Find area of floor:(to find cost of tiles)

40 x 15 = 600m^2

cost: 600 x 3 = 1800pounds

add them if needed

Hope this helps

Good Luck
