$v = x^{3} + 6 x^{2} + 5 x$ $v = x^3 + 6x^2 + 5x$

Explanation:

The formula for volume is: $v = l \cdot w \cdot h$ $v = l * w * h$ where $v$ $v$ is the volume, $l$ $l$ is the length, $w$ $w$ is the width and $h$ $h$ is the height.

Substituting what we know into this formula gives:

$v = (x + 5) (x + 1) x$ $v = (x + 5)(x + 1)x$

$v = (x + 5) (x^{2} + x)$ $v = (x+ 5)(x^2 + x)$

$v = x^{3} + x^{2} + 5 x^{2} + 5 x$ $v = x^3 + x^2 + 5x^2 + 5x$

$v = x^{3} + (1 + 5) x^{2} + 5 x$ $v = x^3 + (1 + 5)x^2 + 5x$

$v = x^{3} + 6 x^{2} + 5 x$ $v = x^3 + 6x^2 + 5x$
