We need to compute the area of the toy chest, which is a rectangular prism. This area is calculated as follows:
[tex]A=2(l\cdot w+l\cdot h+w\cdot h)[/tex]where l is length, w is width and h is height
Substituting with l = 4, w = 2, and h = 4, we get:
[tex]\begin{gathered} A=2\cdot(4\cdot2+4\cdot4+2\cdot4) \\ A=2\cdot(8+16+8) \\ A=2\cdot32 \\ A=64 \end{gathered}[/tex]She will cover 64 square units with paint
