Question

what is the surface area? 2 ft 9 ft 3 ft blank square feet submit

Explanation:

Step1: Recall surface area formula

The surface area $S$ of a rectangular prism is $S=2(lw+lh+wh)$, where $l=9$, $w=2$, $h=3$.

Step2: Calculate each pair product

$lw=9\times2=18$, $lh=9\times3=27$, $wh=2\times3=6$

Step3: Sum the products

$18+27+6=51$

Step4: Multiply by 2

$S=2\times51=102$

Answer:

102 square feet
