The volume of a rectangular prism is given by the formula V=lwh, where I is the length of the prism, w is the width, and h is th

antoniya [11.8K]

Answer:

The answer is $6x^{3} +39x^{2}+54x$

Step-by-step explanation:

Volume of the rectangular prism = Length * Width * Height

Length (l) = $x+2$

Width (w) = $3x$

Height (h) = $2x+9$

By substituting these values to the equation above,

Volume of the rectangular prism = $(x+2)*3x*(2x+9)$

= $(3x^{2} +6x)*(2x+9)$

= $6x^{3} +27x^{2} +12x^{2} +54x$

= $6x^{3} +39x^{2}+54x$

Therefore,

The answer is $6x^{3} +39x^{2}+54x$
