The surface area is quadrupled.
if length and width are doubled then the volume should mulitiply by 8
It quadruples.
if length is doubled then resistivity increases&when area is doubled resistivity decreases.
When the measurements of a rectangular prism are doubled, the surface area increases by a factor of four. This is because surface area is calculated using the formula (2(lw + lh + wh)), where (l), (w), and (h) are the length, width, and height. Doubling each dimension (length, width, and height) results in each area term being multiplied by four, leading to a total surface area that is four times larger than the original.
the surface area quadruples.
if length and width are doubled then the volume should mulitiply by 8
It quadruples.
Assuming no change in the width, yes.
Area = length*width new Area = 2 * length * width Area is doubled
if length is doubled then resistivity increases&when area is doubled resistivity decreases.
The change in the surface area depends on the shape. The volume will double.
The surface area of the 'wall' doubles, but the base areas remain the same.
The Area of a square can be written as it's side length^2, orA = s^2if the side length is doubled, then s' is 2s.A' = (s')^2A' = (2s)^2A' = 4s^2 = 4*AWhen the side length is doubled, the area increases by a factor of 4
Surface Area becomes 4 times the original when its edges are doubled because Suraface area = (edge)^2
this is incorrect -- quick example.. 2"x2"x2" cube -- will have a surface area on each side of 4"sq (2x2=4) --- now make that 4"x4"x4" -- this cube will have a surface area on each side of 16"sq (4x4=16)
the surface area quadruples.
Resistivity is a property of a substance, and doesn't depend on the dimensions of a sample. If the length of a conductor is doubled, then its resistance doubles but its resistivity doesn't change.
