Step 1: Go to Cuemaths online surface area calculator. \begin S = (Lateral SA of large cone) − (Lateral SA of small cone) = π r 1 s − π r 2 ( s − l ) = π r 1 ( r 1 − r 2 r 1 l ) − π r 2 ( r 1 − r 2 r 1 l − l ) = r 1 − r 2 π r 1 2 l − r 1 − r 2 π r 1 r 2 l + π r 2 l = r 1 − r 2 π r 1 2 l − r 1 − r 2 π r 1 r 2 l + r 1 − r 2 π r 2 l ( r 1 − r 2 ) = r 1 − r 2 π r 1 2 l − r 1 − r 2 π r 1 r 2 l + r 1 − r 2 π r 1 r 2 l − r 1 − r 2 π r 2 2 l = r 1 − r 2 π ( r 1 2 − r 2 2 ) l = r 1 − r 2 π ( r 1 − r 2 ) ( r 1 + r 2 ) l = π ( r 1 + r 2 ) l. This is a free online math calculator together with a variety of other free math calculators that compute standard deviation, percentage, fractions, and more.

Rectangular prism:, where a, b and c are the lengths of sides of the prism. Cylinder:, where r is the radius and h is the height of the cone. Cube:, where s is the length of the side. For example, if you are starting with mm and you know r and h in mm, your calculations will result with V in mm 3 and S in mm 2.īelow are the standard formulas for surface area.S = (Lateral SA of large cone) − (Lateral SA of small cone) = π r 1 s − π r 2 ( s − l ) = π r 1 ( r 1 l r 1 − r 2 ) − π r 2 ( r 1 l r 1 − r 2 − l ) = π r 1 2 l r 1 − r 2 − π r 1 r 2 l r 1 − r 2 + π r 2 l = π r 1 2 l r 1 − r 2 − π r 1 r 2 l r 1 − r 2 + π r 2 l ( r 1 − r 2 ) r 1 − r 2 = π r 1 2 l r 1 − r 2 − π r 1 r 2 l r 1 − r 2 + π r 1 r 2 l r 1 − r 2 − π r 2 2 l r 1 − r 2 = π ( r 1 2 − r 2 2 ) l r 1 − r 2 = π ( r 1 − r 2 ) ( r 1 + r 2 ) l r 1 − r 2 = π ( r 1 + r 2 ) l. Here are the surface area formulas: Cone:, where r is the radius and h is the height of the cone. By convention, the volume of a container is typically its capacity, and how much fluid it is able to hold, rather than the amount of space that the actual container displaces. The SI unit for volume is the cubic meter, or m3. The units are in place to give an indication of the order of the results such as ft, ft 2 or ft 3. Surface Area Calculator Area Calculator Volume is the quantification of the three-dimensional space a substance occupies. basearea 2 × × r² Estimation of the lateral surface area is even easier. ![]() There are seven types of prisms based on the shape of the bases of prisms. Solve for those variables, using V as a constant. Write equations for the volume and area of the cylinder in terms of the radius and height. Units: Note that units are shown for convenience but do not affect the calculations. The total surface area of a prism Lateral surface area of prism + area of the two bases (2 × Base Area) + Lateral surface area (2 × Base Area) + (Base perimeter × height).
