Answer:
1008 cm^3
Step-by-step explanation:
First, find the volume of the left rectangular object.
The height is 8cm, the depth is 7 cm and the width is 6 cm
V = 7*6*8 =336 cm^3
Then, find the volume of the middle
The height is 6cm, the depth is 7 cm and the width is 8 cm
V = 7*6*8 =336 cm^3
Finally, find the volume of the right rectangular object
The height is 8cm, the depth is 7 cm and the width is 6 cm
V = 7*6*8 =336 cm^3
Add the volumes together
V total = 336+336+336
= 1008 cm^3
