, where l is length, w is width, and h is height.
For demonstration purposes, the length will be 12 and the width will be 15.
Substituting, we get:

Okay so george and his dad plant 18 to a row and 3 rows an hour. So thats 3 rows of 18 an hour.
So first: Multiply 18 x 3 to find out how many trees they plant each hour.
18 x 3 = 54: So they plant a total of 54 plants each hour.
Next: to find out how many they planted in 8 hours multiply 54 plants x 8 hours
54 x 8 = 432 trees per 8 hours
