Example Question #27 : Surface Area
What is the surface area of a cylinder with height 10 and radius 7?
The formula of the surface area of a cylinder is:
In this problem h is 10 and r is 7. Substituting in those values gives us:
Simplifying and combining the like terms results in:
Example Question #28 : Surface Area
Figure not drawn to scale.
Find the surface area of the box above.
Surface area: 48 yd2
Surface area: 84 yd2
Surface area: 82 yd3
Surface area: 84 yd3
Surface area: 82 yd2
Surface area: 82 yd2
You can find the surface area of a box by following the equation below:
The surface area of the box is 82yd2 (remember that area measurements are square units NOT cubic units)
Example Question #29 : Surface Area
The shaded face of the provided rectangular prism is a square. If the surface area of the prism is , give in terms of .
Since the top face of the prism is a square, the common sidelength - and the missing dimension - is 25.
The surface area of a rectangular prism with length , width , and height can be found using the formula
.
Setting, and solving for :

How many vertices does a polyhedron with twenty faces and thirty edges have?
By Euler's Formula, the relationship between the number of vertices , the number of faces , and the number of edges of a polyhedron is
Set and , and solve for :
The polyhedron has tweve vertices.
Example Question #1 : Faces, Face Area, And Vertices
How many edges does a polyhedron with nine vertices and eleven faces have?
By Euler's Formula, the relationship between the number of vertices , the number of faces , and the number of edges of a polyhedron is
Set and and solve for :
The polyhedron has eighteen edges.
Example Question #131 : Geometry
A rectangular prism has a height of 4 in., length of 8in., and a width of 7in. Find the volume of the prism.
To find the volume of a rectangular prism we use the equation of:
Now substituting in our values we get:
Example Question #2 : Other 3 Dimensional Geometry
What is the volume of a triangular prism having a base of 2, a height of 8, and second height of 14?
To find the volume of a triangular prism we use the equation
In our case our
Therefore,
Example Question #2 : Other 3 Dimensional Geometry
If a cube has a surface area of then what is the the length of its longest diagonal?
The longest diagonal of a cube transverses the interior of the figure:
This distance is defined by the super pythagorean theorem :
where , , and are the length, width, and height. Because the figure is a cube, all three are the same measure, and each is the side of the cube.
We can use the given surface area to find the length of the side:
We can use this value for the side to plug into the super pythagorean theorem
Which can be simplified to
Example Question #1 : How To Graph An Ordered Pair
Which of the following points is in Quadrant IV on the coordinate plane?
Two of these points are in Quadrant IV.
Quadrant IV consists of the points with positive -coordinates and negative -coordinates. Therefore is the correct choice.
