Given:
l = 6cm
w = 3cm
h = 4cm
The formula for the surface area of a rectangular prism is:
[tex]S\mathrm{}A\text{ = 2(lw + lh + wh)}[/tex]
Substituting the given values into the formula, we have:
[tex]\begin{gathered} SA\text{ = 2(6 }\times3\text{ + 6}\times\text{ 4 + 3}\times\text{ 4) } \\ =\text{ 2 }\times(18\text{ + 24 + 12)} \\ =\text{ 2 }\times\text{ 54} \\ =\text{ 108 square cm} \end{gathered}[/tex]
Answer:
Surface Area = 108 square cm
