How do you find the surface area of a 3d object?
It depends, but in let's look at a simple example to help you see how. How would you find the surface area of a cube. Find the surface area of one of the faces and since there are six of those, multiply it by 6. For example, a 2x2x2 cube. Each face has a surface area of 4 and there are 6 of them so the total surface area is 24 units. We do the same thing with other 3d objects, but it may be harder to find the surface area of faces. In face, sometimes there are no faces and we may need calculus to find the surface area.
When would you need to know the volume of a cube?
When asked to work out the lengths of its edges and its surface area.
How do you get the surface area?
To calculate the surface area of an object, you need to determine the area of each individual face or surface and then sum them up. For example, to find the surface area of a cube, you can calculate the area of one face (side) and then multiply it by 6 (since a cube has six equal-sized faces). For a sphere, the formula is 4πr^2, where r is the radius.
How do you find the surface area of an oblique prism?
You will need to find the surface area of each face and add them together.
How do you find the surface area of a rectagle?
to find the surface area of the triangle we just need to multiply the length with breath. area=lengthXbreadth
How do you find the direct proportion between volume and surface area of a cube?
To tackle this you first need to know the equations for both volume and surface area. The surface area of a cube is 6x2 where x is the side length. The volume of the cube is x3. Thus x is the cube root of the volume. We can substitute this in to the surface area equation and say that the surface area of a cube is 6volume2/3 This can also be rearranged to say that the volume of the cube is (the surface area/6)1.5
What is the history of the surface area of a cube?
well to find the surface area of a cube it is really quite simple all you have to do is find the perimeter of one of the bases once you find that you can multiply the perimeter by the height and that is all you need to find it but the history of it was that a man named brendan swineheart

What is the surface area of a cube 8x8x8?
You need units, but the answer is 384 square Whatevers. The surface area of one side is 8*8 = 64 square Whatevers. A cube has 6 equal sides. 64*6 = 384.

A cube with 2 inch sides is placed on a cube with 3 inch sides then a cube with 1 inch sides is placed on the 2 inch cube what is the surface area of the three inch cube?
The bulk of the question is irrelevant ! If all you need is the surface area of the 3-inch cube, simply multiply 3 x 3 x 6 to give 54 square inches !
How do you find the surface area of a hexagon?
The surface area of a hexagon is the same as its area. You will normally need to split the hexagon into triangles, find their area and sum these.
