Step-by-step explanation:
we know that
The volume of the figure is equal to

where
B is the area of the base
h is the height of the figure
Let

Find the area of the base B

substitute

Step-by-step explanation:
Here important information is missing. That is total number of divide.
However, it is given that riley made groups of 12 with 1left over from total number of divide. So, total number of divides on the drawing must be a multiple of 12 +1. It can be any number like 12n+1, where n is an integer. Then we ca find total number of group.
