### 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

### 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&amp;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.

### 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)

### 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

### What change in resistivity if length is doubled?

If the length of a material is doubled, the resistivity remains the same. Resistivity is an intrinsic property of a material and is not affected by the dimensions of the material. However, the resistance of the material will double if the length is doubled, according to the formula R = ρ * (L/A), where R is resistance, ρ is resistivity, L is length, and A is cross-sectional area.

### 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.
