If it's 12 x 14 x 15, it's not a cube.
The surface area of the object is 1116 square centimeters.
Surface area = 2*(12*8 + 8*9 + 9*12) sq cm = 2*(96 + 72 + 108) = 552 cm2
It is: 12*12*6 = 864 square cm
864 inches2
Surface area of sphere = 4*pi*122 = 1809.557368 or about 1810 square cm
864 square feet
Assuming you refer to a 12 cm cube, the answer is 6 * area of one side = 6*144 cm2 = 864 cm2
volume is 12x12x12 surface area is 12x12x6
Surface area = 2*(12*8 + 8*9 + 9*12) sq cm = 2*(96 + 72 + 108) = 552 cm2
6*12*12 = 864 square mm
It is: 12*12*6 = 864 square cm

What is the surface area of a box whose length is 8, width is 3, and height is 4? This box has 6 faces: two rectangular faces are 8 by 4, two rectangular faces are 4 by 3, and two rectangular faces are 8 by 3. Adding the areas of all these faces, we get the surface area of the box: 8 × 4 + 8 × 4 + 4 × 3 + 4 × 3 + 8 × 3 + 8 × 3 = 32 + 32 + 12 + 12 +24 + 24= 136 A cube is a three-dimensional figure having six matching square sides. If L is the length of one of its sides, the volume of the cube is L3 = L × L × L. A cube has six square-shaped sides. The surface area of a cube is six times the area of one of these sides What is the volume and surface are of a cube having a side-length of 2.1 cm? Its volume would be 2.1 × 2.1 × 2.1 = 9.261 cubic centimeters. Its surface area would be 6 × 2.1 × 2.1 = 26.46 square centimeters
It is 12*12*6 = 864 square cm
