Question 10

Using V = lwh , find an expression in factored form for the volume of this prism. Explain the general steps you used to arrive at this answer.

Revolt · Accepted Answer

The volume is V = (x)(6x)(2x - 5) = 6x^2(2x - 5). I substituted the dimensions into V = lwh, wrote 2x - 5 over 1, factored the numerators and denominators, and divided out common factors to simplify.
