Question from Salai, a parent: A swimming pool measures 8m long, 6m wide and 1.5 m deep. The special paint for the pool cost $6per square metre. |
Hi Salai,
Let's look at the bottom first. How long is it in meters? How wide is it in meters? What is its area in square meters? Each square meter costs $\$6$ to paint. How much will it cost to paint the bottom?
Next look at one of the long sides. How long is it? How high is it? What is its area? What will it cost to paint one long side?
What about the other long side and the ends?
