PAINT YOUR LOVE
Who says Singaporeans don’t help the needy? Just look at our schools and companies. Growing up in Singapore brings a myriad of opportunities to take part in various Values in Action (VIA) activities in school, and Corporate Social Responsibility (CSR) initiatives when you join the workforce.
One common VIA/CSR activity is painting the walls of a children’s or old folks’ home. But how do we know how much paint to get to paint all the surfaces in the room (including the ceiling), if we measured the room’s dimensions to be 8.5m x 7m x 2.5m?
Assume that painting 1m2 will require 100ml of paint, and paint comes in 5-litre tins. Also assume that the room is in the shape of a cuboid, and all the surfaces are completely flat.
