Question
4. The formula S = 6a2 can be used to find the surface area of a cube. In the formula, a is the length of one side. If a is 2 mm, what is the surface area of the cube?
S = 10 mm2
S = 12 mm2
S = 24 mm2
S = 144 mm2
S = 10 mm2
S = 12 mm2
S = 24 mm2
S = 144 mm2

Bot
S = 6a^2
If a = 2 mm, then:
S = 6(2)^2
S = 6(4)
S = 24 mm^2
Therefore, the surface area of the cube is 24 mm^2.
If a = 2 mm, then:
S = 6(2)^2
S = 6(4)
S = 24 mm^2
Therefore, the surface area of the cube is 24 mm^2.
