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

Which of the following is equal to the expression above

EleoNora [17]

Answer:

$15 \sqrt[3]{2}$

Step-by-step explanation:

${(27 \times 250)}^{ \frac{1}{3} } = {(27 \times 125 \times 2)}^{ \frac{1}{3} } \\ = {27}^{ \frac{1}{3} } \times {125}^{ \frac{1}{3} } \times {2}^{ \frac{1}{3} } \\ = \sqrt[ 3]{27} \times \sqrt[3]{125} \times \sqrt[3]{2} \\ = \sqrt[3]{ {3}^{3} } \times \sqrt[3]{ {5}^{3} } \times \sqrt[3]{2} \\ = 3 \times 5 \times \sqrt[3]{2} \\ = 15 \sqrt[3]{2}$
