what is the surface area of the prism?
ft²

Explanation:

Step1: Recall surface area formula for rectangular prism

Surface Area = $2(lw + lh + wh)$ where $l=13$, $w=6$, $h=4$

Step2: Calculate each term inside the parentheses

$lw = 13×6 = 78$, $lh = 13×4 = 52$, $wh = 6×4 = 24$

Step3: Sum the terms

$78 + 52 + 24 = 154$

Step4: Multiply by 2

$2×154 = 340$

Answer:

340 ft²
