The area would become four times larger. The area increase is always the perimeter increase, squared. For example. If the sides of a square were quadrupled, the area would become sixteen times larger.
you've given volume dimensions for a rectangular prism of 700 cubic feet. It's surface area would be 480 square feet.
A triangle with the above dimensions would be a right angled triangle.
The height would be 4.8 cm.
Polynomial
If both dimensions are doubled then the area is quadrupled. This is true of any geometric shape.
tripled
starting size n, surface area = 6 x n2; starting size 2n surface area 6 x 4n2 so surface area would be quadrupled.
Then the surface area of the solid would be measured in square feet
If you double the dimensions, then the perimeter is doubled. However, the area is quadrupled. For example, let's say that a side of a square is x units. The perimeter would be 4x, and the area x2. Now, let's double the dimension into 2x. Now, the perimeter is 8x, and the area is 4x2. As you can see, the perimeter is doubled and the area is quadrupled.
It Would Drop Very Slowly And Take A While To Just Hit The Surface, But After It Hits The Surface Nothing Will Happen.
Your weight would decrease. Since weight is dependent on the force of gravity, quadrupling the Earth's mass while tripling its diameter would result in a weaker gravitational pull at the surface, leading to a decrease in weight for objects on Earth.
The area would become four times larger. The area increase is always the perimeter increase, squared. For example. If the sides of a square were quadrupled, the area would become sixteen times larger.
there would be loots of wood
You would need to know the surface area of a cylinder if you are a factory worker at Pepsi. You would need to know the dimensions of the label, so it will fit on the can.
it did
It could be anything.... the question needs to be more specific.
