Answer 1

1. Find the formula for volume of a prism
2. Make up some values for length width and height
3. Double each length
4. Find the volumes for both
5. Divide the larger volume by the lower volume
6. The quotient will give you the volume increase factor.

Answer 3

@Hero is this a rectangular prism formula?

Answer 4

Formula for volume of a prism is the same for any prism if I'm not mistaken.

V = Bh

V = Volume of Prism
B = Area of Base
h = height

Answer 5

You can use rectangular prism. It's the easiest to use anyway

Answer 6

So try it and let me know what you get

Answer 7

9 times?

Answer 8

fingers crossed x) @Hero

Answer 9

What numbers did you use?

Answer 10

if i use a number. is it the same with others?

Answer 11

V = (5cm) (5cm) ( 2cm)

Answer 12

Well, I used some numbers but got a different factor other than 9

Answer 13

V= (25cm2) (25cm2) (4cm2)

Answer 14

but if we dont use any number is it possible?

Answer 15

Okay, it said to double each dimension. You squared each dimension.

Answer 16

Using the correct numbers, you would arrive at the same number I came up with.

Answer 17

i just go continue with the numbers i give?

Answer 18

Do you know how to double (not square) your original dimensions?

Answer 19

i thought if the given is doubled it will squared. or is it times 2?

Answer 20

i can do this. :))

Answer 21

double is not the same as squared

Answer 22

The square of a number is n^2
The double of a number is 2n

Answer 23

so the answer is 8 times?

Answer 24

400 / 50 = 8

Answer 25

correct?

Answer 26

You got it

Answer 27

oh yes! :))
