Question

A rectangular sold has a volume of 640 cubic units. The width is 3 units more than the height and the length is 1 unit more than three times the height. Find the dimension

Answer 1

why did you repost

Answer 2

I didnt understand you

Answer 3

i am sorry i hope someone can explain it better

Answer 4

let height=p
then length=3p+1
width=p+3
now it is given that
(p)(3p+1)(p+3)=640
now solve the eqn and get the dimensions

Answer 5

3p^3+10h^2+3p

Answer 6

@ksrakhilesh now what?

Answer 7

that is
(p)(3p+1)(p+3)=5*16*8
this implies p=5

Answer 8

how come you come up with that 5*16*8

Answer 9

it is a mathematical technique to sole such equations
by rearranging the right part untill it converges with left one

Answer 10

how did you get p=5?

Answer 11

@ksrakhilesh how did you get p=5?

Answer 12

compare terms on both sides
