Surface Area

Surface area is the area of an object’s external layer.

Use the BattleBot “Ankle Biter” as an example.
We will look at its basic external case, respectively.

(Measurements are estimations)

Use Area formulas to calculate the
SA of Ankle Biter’s shell.

= 994.8 sq inches

NOTE: Break it down into smaller sections when
calculating the area.
