Volume of a Rectangular Prism Formula: V = lwh

  • <em>l</em> is length
  • <em>w</em> is width
  • <em>h</em> is height

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify variables</em>

<em>l</em> = 8 ft

<em>w</em> = 4 ft

<em>h</em> = 4 ft

<u>Step 2: Find Volume</u>

  1. Substitute in variables [Volume of a Rectangular Prism Formula]:               V = (8 ft)(4 ft)(4 ft)
  2. Multiply:                                                                                                             V = (32 ft²)(4 ft)
