jhonyy9 (jhonyy9):

so do you know formula for volume of rectangular prism ?

OpenStudy (anonymous):

yes, so do you know the anwser?

jhonyy9 (jhonyy9):

yes but you need calculi too

jhonyy9 (jhonyy9):

ok.

jhonyy9 (jhonyy9):

?

OpenStudy (anonymous):

i do

jhonyy9 (jhonyy9):

so can you write it here now ?

OpenStudy (anonymous):

sure

jhonyy9 (jhonyy9):

than you like being checked ?

OpenStudy (anonymous):

A solid (3-dimensional) object which has six faces that are rectangles. It has the same cross-section along a length, which makes it a prism.

OpenStudy (anonymous):

i need anwser asap, emergency!

jhonyy9 (jhonyy9):

but you need to know formula for volume of rectangle - do you know it ?

jhonyy9 (jhonyy9):

Volum = area of base time height yes ?

OpenStudy (anonymous):

& i just showed u dat i do?

jhonyy9 (jhonyy9):

area of base = ?

OpenStudy (anonymous):

r u asking

OpenStudy (anonymous):

A rectangular prism has three dimensions: length (l), width (w), and height (h). Another way to think about the volume formula is as follows: V = l w h = (l w) h. Since l w is the area of the prism's base, you can think of the volume formula as the area of the base times the height, or V = Bh.

jhonyy9 (jhonyy9):

Area = length time width yes ?

jhonyy9 (jhonyy9):

so than you know these all just you need substituting these values of length and width and height

OpenStudy (anonymous):

ok thanks

jhonyy9 (jhonyy9):

this is easy very

jhonyy9 (jhonyy9):

V = 9*11*3

OpenStudy (anonymous):

it seems hard, can u explain 2 me how to receive answer so i can do the rest?, im horrible at math

jhonyy9 (jhonyy9):

V= 99*3 = ?

OpenStudy (anonymous):

hold on

OpenStudy (anonymous):

297

jhonyy9 (jhonyy9):

yes -- nice

OpenStudy (anonymous):

wait where did u get 99 from?

jhonyy9 (jhonyy9):

do you understand it now ? 99 is area of base what is length time width so 11*9 = 99

jhonyy9 (jhonyy9):

ok. ?

OpenStudy (anonymous):

i get it

jhonyy9 (jhonyy9):

ok. bye

OpenStudy (anonymous):

bye?

jhonyy9 (jhonyy9):

hi

OpenStudy (anonymous):

thanks 4 your help

jhonyy9 (jhonyy9):

was my pleasure

jhonyy9 (jhonyy9):

good luck

OpenStudy (anonymous):

thanks & u 2
