The volume is the space within the inside of a 3D
shape.
Rectangular Prism
We can find the volume of a rectangular prism by multiplying the area of the cross-section (front rectangle) by the length.
Volume of a cuboid
= length × width × height
= lwh
height, h
length, lwidth, w
The area of the rectangle
= length × width
So,
= ldh we use depth or breadth instead of width
Volume of a rectangular prism= length x height x width
