Question

Find the surface area of the rectangular prism with the dimensions listed below.

Answer 1

Given:

l = 6cm

w = 3cm

h = 4cm

The formula for the surface area of a rectangular prism is:

`S\mathrm{}A\text{ = 2(lw + lh + wh)}`

Substituting the given values into the formula, we have:

`\begin{gathered} SA\text{ = 2(6 }*3\text{ + 6}*\text{ 4 + 3}*\text{ 4) } \\ =\text{ 2 }*(18\text{ + 24 + 12)} \\ =\text{ 2 }*\text{ 54} \\ =\text{ 108 square cm} \end{gathered}`

Answer:

Surface Area = 108 square cm
