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
Find the area by multiplying the length times the width. A = L x W A = 12 x 5 = 60 square feet
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.

A cylinder with a radius of 5 centimeters and height of 9 centimeters
The area of triangle is : 25.0
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.
262 cm^2
To find the area of a rectangle, multiply the length by the width. In the case of a 5 cm by 4 cm rectangle, the area would be 20 square centimeters.
5 x 6 = 30 cm2
