Kolby Tran · Answer 1

1.5 cm²

Step-by-step explanation:

Substitute a = 0.5 cm to the formula SA = 6a²:

SA = 6 (0.5) ² = 6 (0.5 · 0.5) = 6 (0.25) = 1.5 cm²

Charlie Mccormick · Answer 2

a = edge length = 0.5 cm

S = surface area of cube

S = 6*a^2

S = 6 * (0.5) ^2

S = 6*0.25

S = 1.5

The surface area of the cube is 1.5 square cm

You can use cm^2 in place of "square cm" to mean the same thing.
