You are the flat surface of three-dimensinal shape?
If you are a cube, one of the sides is called a face. Same with a cone, the flat part is a face.
Are the diagonals of every face of a right rectangular prism the same length?
Sometimes true
If each edge of a cube is 10 in long then what is the area of each face?
Well, honey, since a cube has 6 faces and they're all the same size, the area of each face would be the same. So, if you want to find the area of one face, you can just take one edge and square it. In this case, since each edge is 10 inches long, the area of each face would be 100 square inches. Hope that clears things up for ya!
How do you work out the surface area of a 3D shape?
take 1 face and times the base by height and the times it by the number of faces b * h = area of 1 face area of 1 face * number of faces = surface area note all faces must be the same! Hope i HELPED :D
What is the difference between length width and heigth?
That depends on how you look at an object. For example,imagine you have a cube in front of you and you measure the distance from top to bottom of that face of the cube, call the face f, that is the height. Now turn the cube so the face you were viewing is one the bottom. The same measurement you made of f, the height, is now the width.
