Oh, dude, calculating the cross-sectional area of a cube is like a walk in the park. You just take the length of one side of the cube and square it. So if the side of the cube is 4 units long, the cross-sectional area would be 16 square units. Easy peasy, right?
A perimeter is normally defined for 2-dimensional shapes and not three dimensional ones. A cube has 12 edges. So, if the perimeter is 48 cm, each edge must be 48/12 = 4 cm. The cross section of a cube depends on the angle of the plane intersecting the cube and, if it is not perpendicular to the cube, can be triangular, parallelogram or hexagonal. Assuming the plane is at right angles to the cube, the cross section is a square with sides of 4 cm. So its area is 16 cm2
That would depend on the shape, be it cube, sphere, etc. In general, the volume of any regular solid is its cross-sectional area multiplied by its length.
Total surface area of a cube: 6 times a side squared
Multiply the area of one of its faces by 6
Total Surface Area = 6L2. Where L = the length of one side of the cube.
If you mean what is the right cross sectional area of a cube with a volume of 250 cubic centimeters the answer is 40 cc (really 39.685)
as every size bar differ in diameter and possibly type, the reinforcement steel is measured in kilograms per meter, say 8.5kg/m. the steel weight is actually calculated, as a % of the cross-sectional area. different applications have different minimum % steel required, roughly work on 1%. the sum of the bars cross sectional area at each support and spans are seperately calculated and compared to the cross sectional area of the concrete, hence expressed as a %.

The cross sectional area of a triangular prism is simply the area of the base. The formula for the area of a triangle in one half base times height. Remember that a triangular prism by definition has a triangle for a base.
Multiply the area of one of its faces by 6
Total Surface Area = 6L2. Where L = the length of one side of the cube.
If a cube has sides of length x cm then area = 6x2 cm2 and volume = x3 cm3
Take the length of one side and multiply it by itself - this give you the area of one side. Then multiply it by itself again to give you the area of the cube. For example, if the length of one side was 4cm, you would do 4x4x4, giving you 64 centimetres cubed.
