All graphics volume formulas

Volume calculation formula
Cuboid volume = length × width × height
Volume of cube = base area × height
The volume of cube = edge length × edge length × edge length v = A3
Volume of cylinder
Volume of cylinder = area of bottom × height cylinder v = sh
Volume of cone
Volume of cone = 1 / 3 × bottom area × height v = 1 / 3SH
Spherical volume formula:
The volume formula is v = 4 / 3 × π × R ^ 3
