Answer:
[tex]258 in^2[/tex]
Step-by-step explanation:
Given the dimensions
L = 9 in
W = 6 in
H = 5 in
we can see that the craft is a cuboid/rectangular prism
the expression for the surface area is given as
[tex]Surface -area=2lw+2lh+2hw[/tex]
substituting we have
[tex]Surface- area=(2*9*6)+(2*9*5)+(2*5*6)[/tex]
[tex]Surface -area=108+90+60= 258[/tex]
[tex]Surface -area=258 in^2[/tex]
