It depends on the figure.
There are simple formulae for cuboids (including cubes) and ellipsoids (including spheres). Those for other regular polyhedra and some other shapes are not too complicated, but there are also shapes where there is no option but to calculate the area of each face and sum the individual areas. And, if the shape is completely irregular, even that may not be an option.
To find the surface area of similar figures, you first need to determine the scale factor between the two figures. If the scale factor is ( k ), then the ratio of their surface areas will be ( k^2 ). Multiply the surface area of one figure by ( k^2 ) to find the surface area of the similar figure. This principle applies to any pair of similar shapes, regardless of their dimensions.
The surface area of the 3-D figure will be the total of the areas of the 2-D figures.
Surface area of a sphere = 4*pi*radius2 Surface area = 4*pi*42 => 201.0619298 Surface area of the sphere = 201 square units correct to three significant figures.
The answer to the surface area composite figures riddle activity typically involves calculating the total surface area of a combination of geometric shapes. To solve it, you would find the surface area of each individual shape and then sum them, accounting for any overlapping areas that shouldn't be included twice. It emphasizes understanding how to break down complex shapes into simpler ones for easier calculation.
to find the surface area you have to first find the area of each part then add the areas together.
The surface area of the 3-D figure will be the total of the areas of the 2-D figures.

to find the surface area you have to first find the area of each part then add the areas together.
First find the radius by dividing 19 by 2*pi which is 3.023943919 cm Surface area of a sphere (the ball) = 4*pi*radius2 Surface area = 4*pi*3.0239439192 => 114.9098689 Surface area of the ball: 115 square centimeters correct to three significant figures.

You don't. You can find the area of geometric figures, not of numbers.
The formula to find the surface area of a parallelogram is Base*Height.
The trapezoid is a plane figure which has surface Area, but no volume but if there was a 3d figure your equation would be. The Surface Area of a trapezoid = ½(b1+b2) x h X Height of figure.

Lenght X width = surface area
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.
