Question

Find the surface area of the prism below. Round your answer to the nearest whole number.

Answer 1

Answer:

$333.09\text{ m}^2$

Explanation:

Here, we want to calculate the surface area of the given triangular prism

To calculate this, we use the following formula:

$\begin{gathered} SA\text{ = bh +pl} \\ p\text{ = b + h + c} \end{gathered}$

We have the sides represented as follows:

b = 5 m

h = 3 m

l = 23 m

c = 5.83 m

p = 5 + 3 + 5.83 = 13.83 m

Substituting the values, we have:

$SA\text{ = 5\lparen3\rparen+ 13.83\lparen23\rparen= 333.09 m}^2$
