## Surface Area of a Rectangular Prism Solution

STEP 0: Pre-Calculation Summary
Formula Used
surface_area = 2*(Length*Width+Length*Height+Width*Height)
SA = 2*(l*w+l*h+w*h)
This formula uses 3 Variables
Variables Used
Length - Length is the measurement or extent of something from end to end. (Measured in Meter)
Width - Width is the measurement or extent of something from side to side. (Measured in Meter)
Height - Height is the distance between the lowest and highest points of a person standing upright. (Measured in Meter)
STEP 1: Convert Input(s) to Base Unit
Length: 3 Meter --> 3 Meter No Conversion Required
Width: 7 Meter --> 7 Meter No Conversion Required
Height: 12 Meter --> 12 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
SA = 2*(l*w+l*h+w*h) --> 2*(3*7+3*12+7*12)
Evaluating ... ...
SA = 282
STEP 3: Convert Result to Output's Unit
282 Square Meter --> No Conversion Required
FINAL ANSWER
282 Square Meter <-- Surface Area
(Calculation completed in 00.016 seconds)
