Sungei Buloh

Hope you had fun at Sungei Buloh. For some of you, it may be your first time seeing huge monitor lizards, egrets and so on.

Just wanted to talk a little bit about conversion. There was a question about finding the volume of the pond. The surface area of the pond was 25 square metres and the depth was 6m.

Many of you obtained the volume by multiplying the surface area by the depth.
25 x 6 = 150
The volume is 150 cubic metres.
That is correct.

However, you were supposed to express your answers in litres. How?

The solution:
1 m = 100 cm
1 m x 1 m x 1 m = 100cm x 100cm x 100cm
1 cubic metre = 1000 000 cubic cm
150 cubic metres = 150 000 000 cubic cm

Since 1000 cubic cm = 1 litre,
150 000 000 cubic cm = 150 000 litres

Try to understand.
I will explain this again in class.

Have a good weekend.
