Question

A right rectangular prism has a volume of 40 cm^3. Find the new volume of the prism if only the length of the prism is doubled.

Answer 1

what is the formula for the volume of a rectangular prism?

Answer 2

no picture? Volume of rectangular prism=(w)(l)(h). Here, 40=(w)(l)(h)

Answer 3

let the length = l
Base area =l* w
double means 2 times
if the length is doubled then the base area = (2l)* w

Answer 4

@Bee_see no picture was attached to this question

Answer 5

really don't need one

Answer 6

(21)*w isn't an option o:

Answer 7

important to see the formula and see the change

Answer 8

that was not the answer!!
that was for the new base area

Answer 9

the volume for the prism = Bh where B is the base area and h is the height

Answer 10

Ohhhh

Answer 11

the area of the rectangle is l*w ; length * width
the new area = (2l)* w
the new volume = new base area * height
= (2l)*w*h

Answer 12

now compare the old volume with the new volume to see the effective change with the change in only the length

Answer 13

Oh it's B

Answer 14

I have no idea . I did not see the options.
but do you see how to apply the formula?

Answer 15

40cm^3
