A pack of floor tiles Paint covers 6 m2 oom measures costs EI1.99 per litre. She has currently saved £170. Is this enough?Explanation / Answer
Let's go step by step. We'll focus on the kitchen first.
a) Paint = $4.4/Litre
b) The kitchen measures 3.5m by 7.1m and has a height of 2.5m
c) Paint must be bought in multiples of 5 Litres
d) Paint covers 6m2 per litre
-> Total surface area to be painted : 2(lb+bh+lh) = 2(3.5x7.1 + 3.5x2.5 + 2.5x7.1)
= 51.35m2
The amount of paint to be bought = 51.35/6 = 8.56L
Paint has to be bought in multiples of 5 litres -> So, we need 10L of paint.
Cost to buy paint: 10L x $4.4/L = $44
Answer to PART 1: $44 should be spent on painting the kitchen walls.
PART 2: Tiling the downstairs bathroom floor
1) The tiles are 33cm by 33cm
2) Floor tiles come in packs of 9
3) The downstairs bathroom measures 3.2m by 2.8m
4) The upstairs bathroom measures 5.2m by 3.0m
5) A pack of floor tiles costs $11.99
Area of the floor to be tiled : Down + Up
= (3.2x2.8) + (5.2x3)
= 24.56m2
Area of each tile: 0.33m x 0.33m = 0.1089m2
No. of tiles = 24.56/0.1089 = 225.53 tiles
Since they come in packs of 9 and 9 x 25 = 225, hence 26 packs of tiles are required to make up the number of tiles.
Cost of the tiles = $11.99 x 26 = $311.74
Hence, combining the cost of $311.74 + $44 = $355.74
As this is more than her saved amount of $170, this won't be enough, sadly.
Cheers!
