What happens to the volume of a box when the length width and height are doubled?
The volume of the box will be multiplied byeight.
If the length of a rectangle is doubled and its height quadrupled how is its area changed?
Its area is now eight times greater than its original size. If area = L x H, then 2(L) x (4)H = 8 (original area)
If the length of a square is doubled how is the area affected?
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
How does doubling the side lengths of a triangle affect its perimeter?
If the length of each side is doubled, then the perimeter is also doubled.
What happens to the area of a circle if the diameter is quadrupled?
If the diameter of a circle is quadrupled, the circle's area goes up 16 times as area is proportional to diameter squared. Remember area = pi /4 times diameter squared -------------------------------------------------------------------------- In any ratio of shapes: whatever the ratio of the lengths, the ratio of the areas is the square of that ratio. In this case, the ratio is 1:4, so the areas are in the ratio of 1²:4² = 1:16; ie as the length of the diameter is quadrupled (ratio 1:4), the area becomes 16 times bigger (1:16).
What happens to the current of the wire when the length increases?
resistance is directly proportional to wire length and inversely proportional to wire cross-sectional area. In other words, If the wire length is doubled, the resistance is doubled too. If the wire diameter is doubled, the resistance will reduce to 1/4 of the original resistance.
How does a volume of a rectangular prism change is the length and width is doubled and the height stays the same?
It is quadrupled.
How does the surface area of a cube change if the length of each side is doubled?
The surface area is quadrupled.
What happens to the area of a rectangle when both dimensions are doubled?
It would be 4 times greater.To find this algebraically: let L be the length and W the width originallyA = L x WWhen both are doubled, the equation becomesA = (2L) x (2W) = 4LWThe area of the rectangle is quadrupled if both the length and width are doubled.
What happens to the perimeter of a rectangle when its length and width are quadrupled?
When the linear dimensions of a plane figure are quadrupled, its perimeter is quadrupled, and its area is multiplied by 42 = 16 .
What is the Change in resistance of wire when its length is double?
Assuming the wire follows Ohm's Law, the resistance of a wire is directly proportional to its length therefore doubling the length will double the resistance of the wire. However when the length of the wire is doubled, its cross-sectional area is halved. ( I'm assuming the volume of the wire remains constant and of course that the wire is a cylinder.) As resistance is inversely proportional to the cross-sectional area, halving the area leads to doubling the resistance. The combined effect of doubling the length and halving the cross-sectional area is that the original resistance of the wire has been quadrupled.
What happens to the volume of a Prism if the length is doubled?
If only the length is doubled, the volume is also doubled.If only the length is doubled, the volume is also doubled.If only the length is doubled, the volume is also doubled.If only the length is doubled, the volume is also 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 would the area be doubled tripled or quadrupled if a house has a living room with the dimensions of 10by 15 feet and is going to double the length and width?
tripled
What happen to the area of a square if side is doubled?
Doubling the length of the sides of a square results in the area being quadrupled (four times the original area).
What happens to resistance when length of conductor is doubled without affecting thickness of conductor?
Nothing. Resistivity is a physical characteristic of a material. It's not affected by its shape, etc.
What change in resistivity if length is doubled?
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.
