Answer:
The surface area is [tex]SA=3.596\ m^{2}[/tex]
Step-by-step explanation:
we know that
The surface area of the box is equal to
[tex]SA=2[LW]+2(L+W)H[/tex]
Let
[tex]L=1/4=0.25\ m[/tex]
[tex]W=0.36\ m[/tex]
[tex]H=2.8\ m[/tex]
substitute the values
[tex]SA=2[0.25*0.36]+2(0.25+0.36)(2.8)[/tex]
[tex]SA=0.18+3.416[/tex]
[tex]SA=3.596\ m^{2}[/tex]
