Answer :
Convert 1.3 ft to inches which is 15.6in
then multiply all measurements using the volume formula which is L•W•H
17 * 15.6 * 8 = 2121.6 cubic inches
we know that
the volume of a rectangular prism is equal to
[tex] V=L*W*H [/tex]
where
L is the length of the box
W is the width of the box
H is is the height of the box
in this problem we have
[tex] L=17\ in[/tex]
[tex] W=1.3\ ft[/tex]
[tex] H=8\ in[/tex]
Convert [tex] 1.3 [/tex] feet to inches
we know that
[tex] 1 [/tex] feet is equal to [tex] 12 [/tex] inches
so
[tex] 1.3*12=15.6\ inches[/tex]
[tex] W=15.6 in[/tex]
Find the volume
[tex] V=17*15.6*8 [/tex]
[tex]V=2,121.6\ in^{3}[/tex]
therefore
the answer is
[tex] 2,121.6\ in^{3}[/tex]
