Volume (What Is)

How much space an object takes up

What is a prism and how to calculate

A prism is a solid with 2 congruent polygon bases and connected by rectangles.

They are named after the base shape

V prism = A base x h (area of the base times height)

Cylinder Volume

π r² h or π x r² x h

Pyramid Volume

V pyramid = 1/3 A base x h, The volume of a pyramid is equal to one-third the product of the base area and the height.

Cone volume

A cone is a pyramid with a circle base, so it’s

π r² h/3 or 1/3 πr²h (we use the formula for a circle’s area)

Triangular Prism Volume (remember prisms)

Remember the formula for all prisms

it’s (1/2 b h) x h

Sphere formula

V = 4/3 π r³

Pyramids

V = 1/3 base area x height. or 1/3 L² H (area of a square or l² x height/ 3)

Rectangular Prisms volume formula

Volume = length × width × height → be like (base area) × height
