Step 1: Find the volume of the green figure
The formula for volume is length x width x height
length: 12 in
width: 6 in
height: 12 in
so...
12 x 6 x 12 ---> 72 x 12 ---> 864
For the green figure the volume is 864
Step 2: Find the volume of the blue figure
The formula for volume is length x width x height
length: 18 in
width: 8 in
height: 10 in
so...
18 x 8 x 10 ---> 144 x 10 ---> 1440
For the blue figure the volume is 1,440
Step 3: To find the composite volume add the volume of the green figure to the volume of the blue figure
864 + 1,440 ---> 2,304
Hope this helped!
