What is the surface area of the rectangular prism? 155 in² 270 in² 300 in² 310 in² rectangular prism with length labeled 4 inches, width labeled 5 inches, and height labeled 15 inches155 in² 270 in² 300 in² 310 in²

The surface area of rectangular prism is $310\,\text{i}{{\text{n}}^{\text{2}}}$ .

What is surface area of rectangular prism?

The surface area of the rectangular prism is defined as the sum of the area of lateral faces and rectangular bases.

So, the formula of surface area of rectangular prism is,

$\text{SA = }2lh+2hw+2lw$

Where, $SA$ is the surface area, $l$ is the length, $w$ is the width of the rectangle and $h$ is the height.

It is given that,

$l = 4 in$

$w = 5 in$

$h = 15 in$

Put all the given values in the above formula and solve it.

So,

$\text{SA = }2lh+2hw+2lw$

$=2\left( 4\cdot 15 \right)+2\left( 15\cdot 5 \right)+2\left( 4\cdot 5 \right)$

$=120+150+40$

$\therefore \,\,\text{SA}=310$

Hence, the correct answer is option $d$ that is $310\,\text{i}{{\text{n}}^{\text{2}}}$ .

Write a formula that will help them decide how much each friend will have to pay.Let's let
w = price per mile
x = number of miles traveled
y = number of friends in the cab
z = cost for each friend

Answers

Okay so since we have all the variables, we can go ahead and make our formula. So our equation would look like z = (w/x) divided by y . This is because z would be the sum of the x miles divided by the cost of each mile (w). And then we would divide what we got in the parenthesis by y (friends).

Please help thanks!!!
