Question

Find the surface area of the prism or regular pyramid.

Answer 1

Hint: Use the formula of the surface area of the prism.

Step 1: The given figure is a prism with a length of $5ft$, width of $2ft$, and a height of $3ft$.

Substitute $l=5,w=2andh=3$ into the formula for the surface of a prism:

$$\begin{gathered} S=2\left(5\right)\left(2\right)+2\left(3\right)\left(2\right)+2\left(5\right)\left(3\right) \\ S=20+12+30 \\ S=62 \end{gathered}$$

Step 3: Thus, the surface area of the given prism is $62f{t}^2$

Final Answer: The surface area of the given prism is $62f{t}^2$.
