Ex. 1: Finding the Volume of a rectangular prism
• The box shown is 5 units long, 3 units wide, and 4 units high. What is the volume of the box?
• Here’s how to draw a rectangular prism.
Ex. 1: Finding the Volume of a rectangular prism
L = 5; W = 3; H = 4
V = LWH
V = (5)(3)(4)
V = 60 unit3
Find the height of a prism with a volume of 480m3, length of 12m
and width of 4m.
