Assuming you refer to a 12 cm cube, the answer is 6 * area of one side
= 6*144 cm2 = 864 cm2
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
Surface area of sphere = 4*pi*122 = 1809.557368 or about 1810 square cm
First, note that a surface has area, but a solid figure has volume. There is no such thing as "volume area". Now, to find the volume is easy, assuming all surface angles are right angles. Just multiply .5 * .5 * 6 = 1.5 cubic centimeters. Surface area is a little harder. The surface will consist of two .5 by .5 squares and four .5 by 6 rectangles. (The best way to see this is to draw a picture.) So we have 2 times .25 square centimeters plus 4 times .5 times 6 square centimeters, which equals .5 + 12 = 12.5 square centimeters surface area.
Area = Pi(r)2 - A circle with a radius of 12 centimeters has an area of 452.39 square centimeters.
The area of rectangle is : 180.0
33120 cu cm
113.1 square centimeters.
Area = 1/2*(14+12)*8 = 104 square cm
It depends on the exact configuration of the shape.
The area of a hexagon when the measure of each side is 12 centimeters is approximately 374.12cm2
A regulation size 5 soccer ball has a circumference between 68 and 70 centimeters. This translates into a surface area between 1471.865 cm2 and 1559.718 cm2.
