Answer:
The surface area of cube is 54 sq.ft.
Step-by-step explanation:
Formula of surface area of cube = [tex]6s^2[/tex]
Length of side cube = s = 3 ft
Substitute the value in the formula:
So, Surface area of cube = [tex]6s^2=6(3)^2[/tex]
Surface area of cube =6(9)
Surface area of cube =[tex]54 feet^2[/tex]
Hence the surface area of cube is 54 sq.ft.
