How does the surface area of a rectangular prism change when the length and width and height are doubled?
if length and width are doubled then the volume should mulitiply by 8
What do you think happens to the surface area of a rectangular prism when each length is doubled?
It quadruples.
If the length of a rectangle is doubled does the area double?
Assuming no change in the width, yes.
What happens to the area of a rectangle if one side is doubled?
Area = length*width new Area = 2 * length * width Area is doubled
How does resistivity vary if length and area are doubled?
if length is doubled then resistivity increases&when area is doubled resistivity decreases.
What happens to the surface area and volume when the height of a three-dimensional solid is doubled?
The change in the surface area depends on the shape. The volume will double.
What happens to the surface area of a cylinder if the height is doubled and the diameter of the base is not change?
The surface area of the 'wall' doubles, but the base areas remain the same.
What is the surface area of a cube if its edges are doubled?
Surface Area becomes 4 times the original when its edges are doubled because Suraface area = (edge)^2
If the radius of a sphere is doubled what is going to happen to the surface area?
the surface area quadruples.
If the length of each side of a cube is doubled is the surface area doubled?
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)
By how much does surface area increase if the side of a cube is doubled?
It will increase by a factor of 4; in other words, it will be 4 times greater. Given that all sides of a cube are of equal dimension, I will call this variable dimension x. The surface area is, therefore, x2. If the side of the cube is doubled (2x), then the surface area would be (2x)(2x) = (2x)2 = 4x2. So: x --> 2x (the side length is doubled) x2 --> 4x2 (the surface area is quadrupled)
How will the pressure of an object change if area is doubled?
It won't. The pressure within a hollow object may change if the surface area changes, hence the volume. The total pressure acting on the exterior of a solid object may change if the total surface area changes.
