Answer:
54 cm^2
Step-by-step explanation:
side ( a ) = 3 cm
Formula : -
Surface area ( cube ) = 6a^2
Surface area ( cube )
= 6 x ( 3 )^2
= 6 x 9
= 54 cm^2

Answer: A quadrilateral has 4 vertices.
Step-by-step explanation:
It is given that Felix is designing a clock on a coordinate grid. He graphs the shape of the clock with the vertices (–8, 6), (8, 0), and (8, 6).
If a polygon as n vertices then it has n sides.
Form the given information it is clear that the design on a coordinate grid has 3 vertices. It means the shape has three sides.
