3D Shapes: Surface Area & Volume

Calculate surface areas and volumes of prisms, cylinders, pyramids, cones, and spheres.

Surface Area of 3D Shapes

Find the total surface area of cuboids, cylinders, cones, and spheres by summing the areas of all faces.

Volume of Prisms and Cylinders

Calculate the volume of any prism or cylinder using the cross-sectional area times length formula.

Volume of Pyramids, Cones, and Spheres

Calculate volumes of pyramids, cones, and spheres using the standard formulas — including when to use the ⅓ factor.
