The expanded form of 15,409 would be 15,000 + 400 + 9.
Your 15 would alone be 15,000. The 409 is turned into zeros.
For 409, take the 9 off of the end and keep it by itself, and then add a zero in replace for the 9, which makes 400. 
The 9 should come in at the last part as it is the last number.
Add them all together and you should get <span>15,000 + 400 + 9.</span>

Always know the formula for volume prism because that shape is a prism. 
Formula For PRISM: BH/2 x Height.
So then we are going to solve the triangle first... 7 x 22= 154/2= 77 
Then multiply by the height which is 25. 
77 x 25= 1,925.
So your answer should be 1,925 meters cubed. *Don't forget to write the measurement
