## INTRODUCTION

There are many swimming competitions at the summer Olympics and several pools are needed for the games. The London 2012 Aquatics Centre has an Olympic-sized competition pool, a training pool, and a diving pool.

Imagine that you are part of the construction crew building the London 2012 Aquatics Centre. You have been asked to order the concrete for the three pools and estimate the cost of the concrete. The concrete is used to line the insides of the pools and costs \$60 for one square metre.

## THE PROCESS

1. Visit London 2012 Aquatics Centre to read about the London Aquatics Centre.
2. The competition pool is 50 m long, 25 m wide and 2 m deep. The training pool is 50 m long, 21 m wide and 2 m deep. The diving pool is 25 m long, 21 m wide and 5 m deep.
3. Use a ruler to draw plans for the three pools. Label the dimensions.
4. Calculate the area of the bottom and the four walls of each pool.
5. If it costs \$60 for one square metre of concrete, determine the cost of concrete needed to cover the insides of each pool.
6. If each swimming lane is 2.5 m wide, how many lanes will fit in the competition pool? Explain.
7. Which pool has the largest volume? Explain.
