Formula
Rectangle:
Area = Length X Width
A = lw
Perimeter = 2 X Lengths + 2 X Widths
P = 2l + 2w
Parallelogram
Area = Base X Height
a = bh
Triangle
Area = 1/2 of the base X the height
a = 1/2 bh
Perimeter = a + b + c
(add the length of the three sides)
Trapezoid
Perimeter = area + b1 + b2 + c
P = a + b1 + b2 + c
Circle Try the Online tool.
The distance around the circle is a circumference. The distance across the circle is the diameter (d). The radius (r) is the distance from the center to a point on the circle. (Pi = 3.14) More about circles.
d = 2r
c = pd = 2 pr
A = pr2
(p=3.14)
Rectangular Solid
Volume = Length X Width X Height
V = lwh
Surface = 2lw + 2lh + 2wh
Prisms
Volume = Base X Height
v=bh
Surface = 2b + Ph (b is the area of the base P is the perimeter of the base)
Cylinder
Volume = pr2 x height
V = pr2 h
Surface = 2p radius x height
S = 2prh + 2pr2
Pyramid
V = 1/3 bh
b is the area of the base
Surface Area: Add the area of the base to the sum of the areas of all of the triangular faces. The areas of the triangular faces will have different formulas for different shaped bases.
Cones
Volume = 1/3 pr2 x height
V= 1/3 pr2h
Surface = pr2 + prs
S = pr2 + prs
=pr2 + pr
Sphere
Volume = 4/3 pr3
V = 4/3 pr3
Surface = 4pr2
S = 4pr2

Volume for a cube or rectangular prism is: Length x Width x Height
Surface area depends on the shape. Find the area of all the sides (surfaces) and add them together.
Keep in mind that surface area is in units squared, and volume is in units cubed.

surface area is the sum of all the areas of all the faces...volume is the area of one face times the third dimension(usually depth). It's different for different shapes..but the SA of a square is 6s^2 and it's volume is s^3

I accidentally spilled water on a piece of paper that was lying on my kitchen counter, which is made out of wood. There is some kind of protective glaze on the wood, I think. The ink on the piece of paper ran, and now I can't figure out how to clean it off from the counter. Can you help? Thanks very much.
