Question

. Length of the rectangular prism is 4 ft. The height and width are both 3 feet. Find the surface area of the prism.

Answer 1

Ok, so

Here we have a rectangular prism with the following measures:

-Length = 4ft

-Height = 3ft

-Width = 3ft.

Remember that the surface area of a rectangular prism can be found using:

$SA=2lw+2wh+2lh$

Where "l" is the length, "w" is the width, and "h" is the height.

If we replace our values in the equation given, we got that:

$\begin{gathered} SA=2(4)(3)+2(3)(3)+2(4)(3) \\ SA=24+18+24 \\ SA=66 \end{gathered}$

Therefore, the surface area of the prism is 66 ft2.
