She has this amount because she spent it
Can you please take the pictures again I would love to help you! <3
The perimeter is just the sum of all its sides, in this case, 14+8+14+8 is the perimeter of that one.
now, it gets enlarged with a scale factor of 10, namely it gets blown up 10 times, so the length and the width get blown up that much, thus 10*8 and 10*14.
the new perimeter is then (10*8) + (10*14)+(10*8) + (10*14).
To find the volume of a rectangular prism, you just multiply the length x width x height.
So
1 1/4 x 4 x 3 1/4 = volume (and since they are all centimeters you don't have to worry about converting units)
You can also use decimals instead. So either the above equation or 1.25 x 4 x 3.25 = volume
and if you don't know the decimal for a fraction just pop it into a calculator if you have one, so to find 1/4 as a decimal just do 1 divided by 4 in the calculator. There are ways you can do it without a calculator but it's easier if you have one.
So the volume of this cube would be
16.25
or
16 1/4
