Then the surface area of the solid would be measured in square feet
A circle is a plane figure. A 'circular' solid figure would be a sphere.
The square root of 144 is 12.12 x 12 = 144 so the dimensions would be 12cm by 12cm
A composite Solid is a solid formed by two more more solids. ex. If a qube and a pyramid came together, it would make a house, or a composite solid. :D
In two dimensions the lines would be intersecting lines not perpendicular (I believe this is called transversal, see related link). If you are in three dimensions they would be skew lines, like to jets crossing above you that don't hit each other. One is higher than the other.
that would be a solid B
You have given us three dimensions with no indication of the unit the dimensions are measured in. Square meters are the result of multiplying two dimensions. If the measurements are meters, the volume of the object would be 126,720 cubic meters. If you would like the surface area, ask a more specific question.
square centimetres.
That object would have to be a solid using the lengthxwidthxheight.
No, as it is a gaseous plant it has no solid surface.
the volume would get bigger, and the solid itself would just get bigger.
The dimensions of a gym would best be measured in metres (m) and not kilometres (km).
A solid object, such as a rock or a metal bar, would most appropriately have its mass measured in grams and its volume measured in milliliters.
Physical objects can only be measured in three dimensions: length, width, and height. These dimensions define the size and shape of objects in space. Any additional dimensions would require advanced mathematical concepts like those found in string theory.
An area is measured in square units, so for lengths measured in feet, the area would be measured in square feet.The surface area of a box, is just the sum of the areas of each face, each of which is measured in square units.
A 2D interior will be length times width (a flat shape) as in the area of a floor.A 3D figure would be length times width times depth (a raised shape) as in a box.The units used would depend. A floor would be in feet and inches or metres and centimetres.A 3D figure would be in a similar measurement, but given in cubic units.
A cone would fit the given description
The question cannot be answered because gravity is not measured in pounds: it is measured as acceleration whose dimensions, in your obsolete system, would be feet per second-squared.
