So The Box In The Photo Is An 8th Graders Girls Locker And The Question Says To Find The Surface Area Of The Locker class=

Sagot :

Solution

We are given that

Length (l) = 4ft

Width (w) = 2ft

Height (h) = 3ft

Note: Formula for Surface Area of the Locker

[tex]Surface\text{ }Area=2(lw+lh+wh)[/tex]

Substituting the parameters

[tex]\begin{gathered} Surface\text{ A}rea=2(lw+lh+wh) \\ Surface\text{ A}rea=2((4\times2)+(4\times3)+(2\times3)) \\ Surface\text{ A}rea=2(8+12+6) \\ Surface\text{ A}rea=2(26) \\ Surface\text{ }Area=2\times26 \\ Surface\text{ A}rea=52ft^2 \end{gathered}[/tex]

Therefore, the surface area is

[tex]52ft^2[/tex]
