Question

Find the surface area of a rectangular solid with the given dimensions length 21 feet with 16’ x 7’ give your answer without units

Answer 1

Given the word problem, we can deduce the following information:

Length= 21 feet

Width= 16 feet

Height =7 feet

To determine the surface area of a rectangular solid, we use the formula:

S=2LH+2LW+2WH

where:

S=Surface Area

L=Length

W=Width

H=Height

We plug in what we know:

`\begin{gathered} S=2LH+2LW+2WH \\ =((2)(21)(7))+((2)(21)(16))+((2)(16)(7)) \\ \text{Calculate} \\ S=1190 \end{gathered}`

Therefore, the surface area is 1190.
