Question

3. Calculate the surface area of this rectangular prism. 7.9 m 24.7 m 32.3 m Your answer

Answer 1

Let the 3 lengths of the rectangular prism be:

7.9

24.7

and

32.3

The surface area of a rectangular prism is given by the formula:

`SA=2(lw+lh+hw)`

Where

l is the length

w is the width

h is the height

Let

length (l) = 32.3

width (w) = 24.7

height (h) = 7.9

Substituting, let's find the surface area:

`\begin{gathered} SA=2(lw+lh+hw) \\ SA=2((32.3)(24.7)+(32.3)(7.9)+(7.9)(24.7)) \\ SA=2496.22 \end{gathered}`Answer

2496.22 sq. m.
