1. Volume of a Rectangular Prism
How much will I hold?

2. Definitions
A rectangular prism has 6 sides —opposite sides are equal and parallel
Volume is the amount of space inside a shape, measured in cubic units
7 cm
4 cm
8 cm

3. Three measures in a rectangular prism
Length = 8 cm
Width = 4 cm
Height = 7 cm
Volume is how many cubes will fit into this rectangular prism.
7 cm
4 cm
8 cm

4. Finding the Volume V = l · w · h V = 5 · 4 · 7 V = 140 cm³ l= 5 cm
w = 4 cm
h = 7 cm
Formula…
V = l · w · h
V = 5 · 4 · 7
V = 140 cm³

5. Now you try one! V = l · w · h V = 16 · 18 · 15 V = 4,320 m³ of gold
If we could melt all of the gold produced in the last 500 years and put it together into a box, the sides would be 16 m for length, 18 m for width and 15 m high. How much would it hold?
V = l · w · h
V = 16 · 18 · 15
V = 4,320 m³ of gold
