Question

what is the surface area? 1 cm, 6 cm, 2 cm square centimeters

Explanation:

Step1: Recall surface area formula

The surface area of a rectangular prism is given by $SA = 2(lw + lh + wh)$, where $l=6$ cm, $w=1$ cm, $h=2$ cm.

Step2: Substitute values into formula

$SA = 2((6\times1) + (6\times2) + (1\times2))$

Step3: Calculate inner terms

$SA = 2(6 + 12 + 2)$

Step4: Sum and multiply by 2

$SA = 2\times20$

Answer:

40 square centimeters
