To calculate the volume of concrete needed in a rectangle or square the formula is:**Length** times **Width** times **Depth**: **10m long** times **5m wide** times **100mm deep** = **10*5*0.1**= **5.0m3**

To calculate the volume of concrete needed in a triangle the formula is:**½ Base** times **Height** times **Depth**
