In geometry, a cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex. The cube is the only regular hexahedron and is one of the five Platonic solids. It has 6 faces, 12 edges, and 8 vertices. How many edge are there...

Hint – In this question the length of all the edges are given so the length of a single edge can be taken out by assuming the length of one edge to be a variable x. Use the direct formula for volume of a cube which is $V = {x^3}{\text{ c}}{{\tex...
aWe are coloring the edges of a cube one-by-one. At the beginning none of the edges is colored, and in every step we may color only an edge that is not in contact with a colored edge. How many edges can you color this way the most? 我们上色立方体的边缘逐个。 在开始边缘都没有被...

The surface area of a cube is determined by finding the area of one square by multiplying its length times its width, or by squaring the length of one side, and then multiplying that product by six for each one of the squares. Finding the volume of the cube requires multiplying its lengt...
Jamie counted the number of edges of a cube, Jimmy counted the numbers of corners, and Judy counted the number of faces. They then added the three numbers. What was the resulting sum?( ). A. 12 B. 16 C. 20 D. 22 E. 26 相关知识点: 试题来源: 解析 E Jamie数了数正方体的棱数...
All edges of a cube are expanding at a rate of 7 centimeters per second. (a) How fast is the volume changing when each edge is 5 centimeter(s) cm3/sec (b) How fast is the volume changing when each edge is 12 centimeters? cm3/sec ...
Let E d( n) be the number of edges joining vertices from a set of n vertices on a d-dimensional cube, maximized over all such sets. We show that E d( n)=∑ i=0 r−1( l i/2+ i)2 l i, where r and l 0> l 1>⋯> l r−1 are nonnegative integers defined by n=...
