Question

So the box in the photo is an 8th graders girls locker and the question says to find the surface area of the locker.

Answer 1

Solution

We are given that

Length (l) = 4ft

Width (w) = 2ft

Height (h) = 3ft

Note: Formula for Surface Area of the Locker

$Surface\text{ }Area=2(lw+lh+wh)$

Substituting the parameters

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

Therefore, the surface area is

$52ft^2$
