The cube would have a total surface area of 24 Sq. Ft.
24 sq in.
The surface area is 6*52 = 150 sq metres.
4 times 4 equals 16. 16 times 6 (the number of sides) is 96. Therefore, the surface area of a cube with 4 foot long edges is 96 feet squared.
Each face of a cube is a square. If the edges are 3-ft, then the area of each square is 9 square feet.
