Aclosed rectangular tank measures 12 meters by 6 meters by 10 meters. find the surface of the tank

Surface area of rectangular prism = 2lw+2lh+2wh
SA=2(12*6)+2(12*10)+2(10*6)
SA=2(72)+2(120)+2(60)
SA=504
the surface area of the tank is 504m²

The S.A. of the tank is:

12*6 = 72*2 (since there are 2 of the same sides) = 144.
12*10 = 120*2 = 240
6*10 = 60*2 = 120

Then, you add all of the numbers up.
144 + 240 + 120 = 504

So, your surface area of the tank is 504 square meters.
