split the wedge into a triangle and a and rectangle or square. Then calculate the surface area for each shape and add them together
Surface area of a shape depends on what shape you have in mind.
because for a 3d shape you use surface area which is the same except you calculate the area of each side and then add them together
If it's just the front surface of a box then it's simply a 2D shape, the area can be calculated by multiplying the length by the width. Answer will be in units squared.
The most direct way to calculate the area of an irregular shape is to superimpose it on graph paper, and then count the number of complete squares that it covers, and for squares that are only partially covered, estimate how much of the square is covered to the nearest simple fraction (a half, a third etc.). If you want the surrounding area rather than the area of the shape itself, you could calculate the total area and then subtract the area of the shape.
It depends on the shape whose surface area you are interested in.
The surface-area-to-volume ratio may be calculated as follows: -- Find the surface area of the shape. -- Find the volume of the shape. -- Divide the surface area by the volume. The quotient is the surface-area-to-volume ratio.
You measure or calculate the surface area; you measure or calculate the volume and then you divide the first by the second. The surface areas and volumes will, obviously, depend on the shape.

we can use integration.- multiple integration.
That would be called surface area. The way to calculate surface area varies depending on the shape of the surface. A quick google search such as "how to find surface area of a sphere" should solve your dilemma.
The method usually fits into one of two general categories: 1). Use the formula that has been developed for the surface area of that particular shape. 2). Break the shape down into pieces with shapes for which the formula for the surface area has been previously developed, and then apply the method of Category #1.

You need to:* Calculate the surface area * Calculate the volume * Divide the surface area by the volume
