The volume of a rectangular prism is:
V=(length x width x height)
In this figure, we have two rectangular prisms:
1)We calculate the volume of a left rectangular prism:
Data:
length=5 in
width=7 in
height=1 in
Volume₁=length x width x height =(5 in)(7 in)(1 in)=35 in³
2)1)We calculate the volume of a right rectangular prism:
Data:
length=9 in
width=7 in
height=4 in
Volume₂=length x width x height =(9 in)(7 in)(4 in)=252 in³
The volume of the figure below would be the sum of the both rectangular prisms:
Volume of the figure below=Volume₁+Volume₂=35 in³+252 in³=287 in³
Answer: the volume of the figure below would be 287 in³.
