What is the surface area of the cube with the given edge length, s? drag and drop the surface area into the box to match the edge length. s = 2.3 cm 13.8 cm²31.74 cm²132.65 cm²148.04 cm²

For this case we have that by definition the surface area of the cube is given by:

Where,

In this case we have that the side of the cube is given by:

Therefore, replacing values we have:

The surface area of the cube is given by:

Option 2

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
