Answer :
2430 in³
1) Gathering the data
l= 2w
width: 9"
and height:15
2) Considering the volume of this block is given by:
[tex]\begin{gathered} V=a\cdot b\cdot c \\ V=9\cdot15\cdot18 \\ V=2430in^3 \end{gathered}[/tex]Where a=width, b=length, and c= height. And assuming the shape of this block.
3) Hence, the volume is 2430 in³
