First set up the equation based on the description.

x + 16 = 3x
Use subtraction to get the "x"s on one side of the equation. You can next subtract <span>

x from both sides.
16 = </span>

<span> x
Now you can multiply both sides of the equation by </span>

<span> to solve for x
x = 6</span>

<h3>Surface area of rectangular prism is 220 square units</h3><h3>Volume of rectangular prism is 200 cubic units</h3>
<em><u>Solution:</u></em>
<em><u>The surface area of rectangular prism is given as:</u></em>
A = 2(wl + hl + hw)
Where,
l is the length
w is the width
h is the height
From given,
l = 10 units
w = 4 units
h = 5 units
<em><u>Substituting the values we get,</u></em>

A = 2(40 + 50 + 20)
A = 2(110)
A = 220
Thus surface area of rectangular prism is 220 square units
<h3><u>Volume of rectangular prism</u></h3>

Thus volume of rectangular prism is 200 cubic units
