Question

State a formula for determining the volume of a rectangular prism with height 3x, length 4x, and width 5x.

Answer 1

Do you know how to find the volume of a rectangular prism?

Answer 2

If you were given 3 for the height, 4 for the length and 5 for the width, for instance .. ?

Answer 3

Yes.. V=Bh

Answer 4

or lwh

Answer 5

where your B is the area of your base. So you just do the same using 4x, 3x and 5x.

Answer 6

What I did was.. (3x)(4x)(5x).. then it would make 60x.. so Idk what would be right..

Answer 7

yeah, you're close, but your multiplication is done incorrectly

Answer 8

Oh..

Answer 9

when you multiply three x's together you get \x^3

Answer 10

ohhh that's right..

Answer 11

so you want 60x^3

Answer 12

\[60x ^{3}\]

Answer 13

Ah ok so then that would be my formula?

Answer 14

yes

Answer 15

Thank you so much!

Answer 16

No prob.

Answer 17

The volume of a rectangular prism can be found by the formula:
volume=length*width*height.
V = (4x) (3x) (5x)
V = 60 x ³
