The Draw button is not working for me which makes it harder to explain.  But a drawing would make it easier to understand.

Convert everything to inches.  7 feet = 7x12 = 84 in.  6 ft = 72 in.
First step is: 7 x 11 x 84 = ? cubic inches
Second step is: 14 x 11 x 84 = ?
Third step is: 21 x 11 x 84 = ?
Porch is: 28 x 72 x 84 = ?

Add up the 4 numbers on the right hand side and you will get the volume of concrete in cubic inches.
