Question

solve on paper. then check your work on zearn. the surface area of the prism is square units.

Explanation:

Step1: Identify the prism's dimensions

Assume the prism has length $l$, width $w$, and height $h$. From the image, if we assume each small - cube has side - length 1 unit. Let's say the base has dimensions $1\times1$ and the height is 5 units. So $l = 1$, $w = 1$, $h = 5$.

Step2: Recall the surface - area formula for a rectangular prism

The formula for the surface area $S$ of a rectangular prism is $S=2(lw + lh+wh)$.

Step3: Substitute the values into the formula

$S = 2(1\times1+1\times5 + 1\times5)$
$S = 2(1 + 5+5)$
$S = 2\times11$
$S = 22$.

Answer:

22
