Answer: Add all the sides.

For Example: A square has a perimeter of 4,10,3,5. Add 10+4+3+5 and you get 23.

If you was finding Area of a shape you'll multiply 2 sides. Example: A square has 3,4,4,3. Multiply 3*4 and get 12.

The length, width, and height of a right rectangular prism are multiplied by 23. What will be the effect on the volume of the pr

Yanka [14]

Since none of the options make sense with 23, I assume it was a typo, and you meant 2/3.

Let l,w and h be the length, width and height of the original prism, and l',w' and h' be the length, width and height of the new prism. We are given

$l' = l\times \cfrac{2}{3},\quad w' = w\times \cfrac{2}{3},\quad h' = h\times \cfrac{2}{3}$

Also, if we call V the original volume, and V' the volume of the new prism, we have

$V = lhw,\quad V'=l'h'w'$

Substitute the expressions for l', h' and w' in the formula for V':

$V'=l'h'w' = l\times \cfrac{2}{3}\times w\times \cfrac{2}{3}\times h\times \cfrac{2}{3} = l\times h \times w \times \cfrac{2}{3}\times\cfrac{2}{3}\times\cfrac{2}{3} = V \times \left(\cfrac{2}{3}\right)^3 = V\times\cfrac{8}{27}$

4^ sqrt(400) / (4^ sqrt(5))
= 4^20/ 4^ sqrt(5)
= 4^ (20- sqrt(5)

The final answer is 4^ (20- sqrt(5)~
