Question

the width of the rectangular prism is 1 the height is 1 and the length is 4 what is the surface area?

Answer 1

To find the surface area of a rectangular prism, you can use the formula:

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

where \( l \) is the length, \( w \) is the width, and \( h \) is the height.

For your rectangular prism:
- Width (\( w \)) = 1
- Height (\( h \)) = 1
- Length (\( l \)) = 4

Now, plug in the values:

\[
\text{Surface Area} = 2(4 \cdot 1 + 4 \cdot 1 + 1 \cdot 1)
\]
\[
= 2(4 + 4 + 1)
\]
\[
= 2(9)
\]
\[
= 18
\]

So, the surface area of the rectangular prism is **18 square units**.
