What happens to the surface area of a cube if each side is tripled in length?

Similarly when length is tripled (x = 3) surface area is increased ninefold (32 = 9) and volume is increased twenty-sevenfold (33 = 27).

What would be the effect on the surface area of a cube if the length of each edge is doubled?

If each side length is doubled, then the surface area of each face becomes 6(2x)2 = 6(4×2) = 24×2. The volume of a cube with side length x is x3. Each of the edge lengths in the cube are then doubled.

What will be the percentage increase in the surface area of the cube whose side is increased by 50 \%?

125\%
Detailed Solution. Each side of the cube increased by 50\%. ∴ The percentage increase in the surface area is 125\%.

How do you find the percentage increase of surface area?

To calculate the percentage increase:

1. First: work out the difference (increase) between the two numbers you are comparing.
2. Increase = New Number – Original Number.
3. Then: divide the increase by the original number and multiply the answer by 100.
4. \% increase = Increase ÷ Original Number × 100.

How many times do the volume and surface area of a cube increases if its edges gets tripled?

When the edge is tripled, then. = 27 * V. Hence, the volume will increase 27 times. Hence, the surface area will increase 9 times.

What will be the change in the volume of a cube when its side becomes three times the original side?

Volume of cube \(=x^3\) cube units. So, the new volume \(= (10x)^3=1000x^3\) cube units. Thus, The new volume \(= 1000 \times\) the original volume.

What is the percentage change in the volume of a cube if its edge is doubled?

If the edge of cube will be doubled then the volume will be 8 times . and if edge of cube will be halfed then the volume will be 1/8.

How does the total surface area of a cube change if each dimension is doubled?

: Let the length of the edge of the cube be ‘x’ cm (i) Total surface area = 6×2 cm2 Increased length of the edge = 2x Total surface area = 6(2x)2 cm2 = 24×2 cm2 If the edge of the cube is doubled surface area of the cube increases by 4 times.

When a metal cube is heated its sides expand by 2\% find the approximate percentage increases in its volume and surface area?

A circular metal plate expands under heating so that it radius increases by 2.

What will be the percentage increase in the surface area of a cube?

Therefore, the percentage increase in the surface area of a cube is 125.

Is age of a cube is increased by 50\%?

After 50\% increase, each edge of the cube becomes 150/100 of the original. Thus, the surface area of the cube becomes (150/100)^2 = 225/100 of the original. Hence, increase in perecentage of surface area = (225-100) = 125\% .

What is the area of the cube if the edges are increased?

If the edges are all increased by 15 \%, the area of each of the six sides would increase from a 2 to ( 1.15 a) 2 = 1.3225 a 2. That is, the area of each side would increase by 32.25 \%. It follows that the area of the cube would increase by 32.25 \%. In case the last step isn’t clear, let’s look at it in detail.

What is the surface area of a cube with 6 faces?

A cube of side a, has six faces each of surface area a^2. So the total surface area is 6a^2. When each edge is increased by 150 \% each edge becomes 2.5a and the surface area of each face is (2.5a)^2 = 6.25a^2, and 6 faces add up to 6*6.25a^2 or 37.5a^2.

What is the relationship between surface area and volume?

A factor of change to a length, translates into a factor of change to surface area, and it would translate into a factor of change to the volume. The generalization is true for any scale-up (or scale down) of any solid, by any factor.

What will be the percentage increase in volume?

Percentage increase in volume will be 33.1\%
