If the width and height of a rectangular prism are each shrunk to one seventh of the original size but the length remains the same, what is the formula to find the modified surface area

SA =

Step-by-step explanation:

The surface area of a rectangular prism is given by :

Where l stands for length

w stands for width

h stands for height

Given is - If the width and height of a rectangular prism are each shrunk to one seventh of the original size but the length remains the same.

So, length = l

width =

height =

The new surface area will be =

SA =

Simplifying this we get:

SA =

There are many other ways to write this but it has the same meaning, so, we can take this as the answer.

SA =

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

step-by-step explanation:

i found the koficent of the linear function and i foun c acordind to the strict formula y=kx+c and then i took 2 as an x and replacet it on the formula i found and then foun the y
