determine the length of one edge of a cube that has a surface area of 864 square inches.
864 inches2
864 square feet
It is: 12*12*6 = 864 square cm
SA = 864 square feet.
determine the length of one edge of a cube that has a surface area of 864 square inches.
864 inches2
864 square inches.
6*12*12 = 864 square mm
The number 864 is "eight hundred sixty-four."
864 square feet
It is: 12*12*6 = 864 square cm
surface area for a cube isSA= 6a2a2 is the area of one sidearea is L X WSo the answer to your question is: 864 square inches.SA= 6 X 122inchesSA= 6 X 144square inchesSA= 864 square inches
Total surface area = 864 cm2Area of each face = 1/6 of that = 144 cm2Length of the side of the cube = sqrt(144) = 12 cmVolume = 123 = 1,728 cm3
SA = 864 square feet.
6 x (12 x 12) = 864 sq. feet
i assume you mean that the length of one edge of the cube is 12 feet. if so: there are 6 faces on a cube each face is a square the area of a square is it's side squared so... 6(12x12) = SA 6(144)=SA 864=SA 864 ft squared is the surface area
