How do you find the volume of this, please say answer and show work

To find the volume of the object we need to notice that is is made from two rectangular prisms:
• A prism with length 8 cm, width 6 cm and height 13 cm.
,• A prism with length 3 cm, width 4 cm and height 7 cm.
Hence the volume is the sum of the volumes of the prisms.
The volume of a rectangular prims is given by:
[tex]V=lwh[/tex]Hence the volume of the object is:
[tex]\begin{gathered} V=(8)(6)(13)+(3)(4)(7) \\ V=624+84 \\ V=708 \end{gathered}[/tex]Therefore, the volume of the object is 708 cubic cm.
