The formula is 6s2 so 6(2.2)2 is equal to about 29 or 29.04 to be exact
For a cube with sides of length x, surface area = 6x2 and volume = x3.
To determine the surface area of a rectangular prism, the two sides, adjacent sides, and ends of the prism must be added up. To do this, the sides are the product of the prism's length and height, the adjacent sides the width and height, and the ends the product of the length and width.
Assuming the cross-section is an equilateral triangle with sides of 'a' and the length is 'b' the surface area will be 3ab + SQRT(3).a2
use a ruler to measure the sides then do length times width
"Surface area" is the covering of a multi-dimensional body. It is the area that the outside of a body has.For exampleA cube has a surface area of 6 * L2 where L is the length of one side. (six sides to the cube, each is a square with area L * L)
The length of one of its sides is 10 cm.
If the length of the sides triples, the surface area increases 9-fold.
The surface area depends on the shape, not just the length of sides.
ok, so think about it. a cube has 6 sides. The surface area is the area of the surface of all 6 sides combined, so you divide the surface area by 6. This gives you the area of each square on each side. Then square root the answer because the area of a square is the side length squared. Now you have the edge length!
For a cube with sides of length x, surface area = 6x2 and volume = x3.
To determine the surface area of a rectangular prism, the two sides, adjacent sides, and ends of the prism must be added up. To do this, the sides are the product of the prism's length and height, the adjacent sides the width and height, and the ends the product of the length and width.
Yes, if it remains a cube.
Surface Area of a cube is equal to the sum of the area of it sides. Each of its sides are square of side length a. Each side has area of a2. There are 6 sides on a cube. a2 + a2+ a2+ a2+ a2+ a2 = 6a2 Therefore: Surface area of a cube is 6a2
If the surface area of a cube is 294cm^2, the length of one side is equal to the square root of (294/4), which is approximately 8.57cm.
You can think of a square prism as a die, having six sides. So you need the length of one side, 's'. That side's [surface] area is s2 With six sides, the cube's surface area is simply: 6s2
With sides of length A, B and C units, the total surface area is 2*(AB + BC + CA) square units.
Assuming the cross-section is an equilateral triangle with sides of 'a' and the length is 'b' the surface area will be 3ab + SQRT(3).a2
