5 x 12 = 60 sq. cm
Surface area = 314.2 cm2
12 inches to the foot and 2.5 centimeters to the inch = (5 x 12) + 5 = 65 inches x 2.5 to get centimeters =162.5 centimeters
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.
5 x 6 = 30 cm2
You haven't given the units (inches or centimeters or what?) Anyway the hypotenuse is irrelevant all you need to find the area of a right angle triangle is the length of the other two sides. The formula is 1/2(W x H) = A. Which means half the width x the height gives you the area. In this case the width is 5 and the height is 12 which multiplied together gives 60 (the area of a rectangle of 5 x 12). You then need to half it to find the area of the right angle triangle and the answer is 30. Now you just need to know the units.
It is the sum of the areas of all the components.
For a radius of 5 centimeters the area are 78.53981633974483 square centimeters.
A square with a side length of 5 centimeters has an area of 25 square centimeters.
