The answer depends on what information about the block you do have. If you have its length, breadth and height, then the area is 2*(L*B + B*H + H*L) square units.
To calculate the cross sectional area of a rectangular tube, multiply the widths of two adjacent sides of the tube.

perimeter of rectangle=2(l+b) l=length of the rectangle b=breadth of the rectangle
First of all you need to calculate the area of the rectangular field. You do this by multiplying the length by the width. 72m x 388m = 27,936m2 If a square (which has four equal sides of course) has the same area then we can calculate the length of a side by finding the square root of the above. 27,936m1/2 = 167.14m (to 2 decimal places).
It depends on the cross section which may be circular, elliptical, square, rectangular or of a more complex shape.
This will usually be the case for objects that have different shapes: even if they have the same volume, it is unlikely that they have the same surface area. As an example, calculate the volume and surface area of the following two rectangular block shapes: 1) A 2 x 2 x 2 rectangular block 2) A 1 x 1 x 8 rectangular block
Area = Length * Breadth.
To calculate the cross sectional area of a rectangular tube, multiply the widths of two adjacent sides of the tube.
Surface area = 2ab + 2bc + 2ac
If the room is rectangular, the area is the product of its length and width.
area of an box is length x width.

Formula: S = 2B + L
No. Lithium is an s-block element. The d-block metals are the ones in the large rectangular area in the middle of the periodic table.
The same as you would calculate any other area. For example, if the base happens to be rectangular, you multiply length x width.
You cut the shape down into smaller shapes that you recognise and know how to calculate the area of. Then calculate the area of the small shapes and add the all up.
