A closed 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.
