Lateral area of a cube?
A cube with sides of s units has a total surface area of 6*s^2 square units.
In a unit cube what is the largest square you can have inside?
The largest square that you can fit in any cube will have each corner 1/4 of the way away from a corner of the cube and will have a side length of s*3√2/4 where s is the length of the sides of the cube. For a unit cube, the side length is 1 by definition, meaning that this largest square will have a side length of 3√2/4 and that its area will be 9/8 units squared.
How can I figure the dimensions of a perfect cube if the hypotenuse through the center of the cube is 35cm?
Somehow I messed up andused 31 instead of 35 That is why you are receiving an improvement Do a Google search for Diagonal of a cube Find this website. mathcentral.uregina.ca/QQ/database/QQ.09.04/brett1.HTML - Draw a cube You will see how to find the diagonal of a cube. You use Pythagorean Theorem Draw a cube Label each side as s Draw the diagonal of the base of the cube Diagonal of base = (s^2 + s^2 )^0.5 Let the diagonal of the base be the horizontal side of the right triangle whose hypotenuse is the diagonal of the cube. The height of the cube is the vertical side of the right triangle whose hypotenuse is the diagonal of the cube. Now determine the length of the diagonal of the cube. (diagonal of base)^2 + (height of cube)^2 = (diagonal of cube )^2 Diagonal of base = (s^2 + s^2 )^0.5….Height of cube = s Use Pythagorean Theorem (diagonal of cube )^2 = (diagonal of base)^2 + (height of cube)^2 (diagonal of base)^2 = [(s^2 + s^2 )^0.5]^2 = s^2 + s^2 height of cube)^2 = s^2 (diagonal of cube)^2 = (s^2 + s^2 + s^2) (diagonal of cube )^2 = (3 * s^2) diagonal of cube = (3 * s^2)^0.5 = 35 (3 * s^2)^0.5 = 35 Square both sides 3s^2 = 31^2 = 1225 s^2 = 408.33 s = 40833^0.5 s = 20.2 cm
What is the greatest distance between two vertices of a cube with length s?
It is s*√3, easily proved using Pythagoras's theorem.
What is the formula for volume of a cube?
If the length of an edge of a cube is s units then its volume is s*s*s or s3 cubic units.
