Volume of rectangle formula - Office Equipment & Supplies

Formula For Average Gallons In Rectangle, Square Or Freeform Pools:
Length x Width x Average Depth x 7.5 = Total gallons
Formula For Average Gallons In Circular Pools:
Diameter x Diameter x Average Depth x 5.9 = Total gallons
Formula For Average Gallons In Oval Pools:
Length x Width x Average Depth x 5.9 = Total gallons
Formula For Average Depth Of Pools With Slopes:
Shallow End Depth + Deep End Depth Divided by 2 = Average Depth

Multiply the length by the depth to get 100 meters squared.

Volume of a right circular cylinder of radius r and height h is
V=PI*(r^2)*h
Figure out which is the radius and which is the height, then plug in the formula above. Result is in cm^3

A rectangle is a 2D figure and is not a solid. Its area is the product of one side by the other side. Area =length*width.

Each solid with a regular shape has a formula by which its volume is calculated. Once you know the formula to use and the values of the dimensions, just enter it in the calculator as it appears on paper (almost) and press enter/EXE/=
Make sure that the values of sides, radii, heights that are involved in formula must be expressed in the same unit.
The resulting value of the volume has unit
Unit_volume= (Unit of length used)^3

Each specific solid (shape) that has some regularity has a formula which can be used to calculate its volume. If it has no regularity the calculation will be more complicated.
For a right rectangular prism with dimensions L, W, H the volume is L*W*H. For a right circular cylinder with radius r and height H, the volume is Pi*r^2*H.
Once you know the formula, it is an easy matter to use the calculator to evaluate the volume.

At the bottom of the screen )in the default configuration) there are two rectangles. Tap the screen near the vertical line that separates the two rectangles. A Volume slider will appear. Use your finger to move the bead (button) to the right to iincrease volume.

There isn't a single formula for solids of different shapes. For a right solid with a rectangular base - volume is base area x height Similarly for cylinder with a circular base - volume = base area x height (base area in this case is Pi x radius2). For a sphere - volume = 4/3 x Pi x radius3

The diameter of the circle is the diagonal of the rectangle use Pythagoras this rectangle is a made from two 3,4,5 triangles, so the diameter is 5cm, the radius will be 2.5cm don't forget the BODMAS ordering rule (Brackets of Division Multiplication Addition and Subtraction) Also rounding to 2 decimal places. This solution is based on all four corners of the rectangle touching the circumference of the circle.

Area of a circle is P (22/7) i x Radius (squared ^2) ====> 22/7 x 2.5cm ^ 2 ====> 22/7 x 6.25cm

TOTAL AREA of CIRCLE = 19.64 cm^2

Area of the rectangle is length x width ====> 4 cm x 3 cm

TOTAL AREA of RECTANGLE = 12 cm ^2

The remaining portion is the circle area minus the rectangle 19.64-12 = 7.64 cm^2

Your field, terrain, figure has a particular form. For each form you have a formula that tells you how to compute the area enclosed. Read your book or your notes to know what formula to use. I cannot give you a formula because I have no idea about the shape of the figure nor its dimensions.

Now, having the formula at hand you can use your calculator to calculate the area. But, in order to obtain consistent values you must convert all dimensions to the same unit length: m, cm, km, inches, feet or what have you.

For example: You have a rectangle with LENGTH L=3.5 m, and a width W=20 dm (decimeters), you must convert the value in decimeters to meters, 20 dm=2 m.
The area of you rectangle will be
Area=L*W=(3.5 m)*(2 m)=3.5*2 m*m= 7 m^2
