Speed Crunch performs all of the functions necessary for high school Algebra and Geometry courses. SpeedCrunch is a good free alternative to buying an expensive scientific calculator.
A cube is a three-dimensional figure with six matching square sides.
In a rectangular box, the length, width and height may be of different lengths.
l = length of box w = width of box h = height of box
SpeedCrunch colors the expression according to the syntax. You can easily distinguish numbers from variables. You can also see the matched parentheses.
A pyramid is a solid with a polygon base and connected by triangular faces to its vertex. A pyramid is a regular pyramid if its base is a regular polygon and the triangular faces are all congruent isosceles triangles.
l = length of base w = width of base h = height of pyramid
c and d = slant height of pyramid face (c= length face & d = width face)
SpeedCrunch has unlimited variable storage and more than 50 built-in math functions.
A trunctated pyramid volume is one third the height times (A + sqrt(A*B) + B)
where A and B are the area of the top and bottom faces.
A= area (A*B) and B= area (C*D)
In SpeedCrunch variables need not be only a character, "InterestRate" is a perfect name as well. And still, you can define as many variables as you want.
There is a special variable, ans, which always holds the last calculation result.
A sphere is a solid with all its points equal distance from the center.
r = radius of sphere
In SpeedCrunch you just type the expression that you want to calculate and press Enter. You can see clearly what you typed along with the result in the scrollable display.
a= large radius of segment
b= small radius segment
h= height of segment
R= radius of sphere
In SpeedCrunch you can paste the expression from the clipboard, that you copied from somewhere else. And, you can quickly copy the last calculation result to the clipboard using Ctrl+R.
fig. 15 Sphere 2 base segment Volume and Surface Area
Volume = (π/3)h²(3R-h)
Surface Area = 2πRh

In geometry, a spherical cap is a portion of a sphere cut off by a plane.
The expression: A = 2*π*r*h:
R = radius of sphere
h = height of cap
a = radius of the cap (or plane)
SpeedCrunch Math book is a small library that contains the formula for 2D/3D objects and quadratic equations.
The part of a sphere between two right circular cones that have a common vertex
at the center of the sphere, and a common axis.
SpeedCrunch allows you to save your session so that you can resume from where you stopped the last time. Your history and variables will be intact the next time you load up the session.

Volume = (2/3)πR²h
Surface Area = 2πRh

Good news: Most polygons on the SAT have just four sides. You won’t have to tangle with any dodecahedrons on the SAT you take. There are five different types of quadrilaterals that pop up on the test. These five quadrilaterals are trapezoids, parallelograms, rectangles, rhombuses, and squares.
A circle is the collection of points equidistant from a given point, called the center. A circle is named after its center point. The distance from the center to any point on the circle is called the radius, (r), the most important measurement in a circle.
Triangles pop up all over the Math section. There are questions specifically about triangles, questions that ask about triangles inscribed in polygons and circles, and questions about triangles in coordinate geometry.
