What is area? Area is the space that a 2D object takes on something. Here are some formulas to some common shapes (2D objects). Square = a2 Rectangle = ab Parallelogram = bh  Trapezoid = h/2 (b1 + b2)

Circle = //pi// r 2 Ellipse = //pi// r Triangle = (1/2) b h

Volumes are the amount of space a 3D substance take up. For example, if there is a cube 1cm high, 1cm long and 1cm wide, its volume would be 1 cubic cm. That seems pretty easy, didn't it? But what if its length was 143m, its width was 36m, and its height was 567m high? Then you need some formulas.

what is volume?how do you calculate volume? volume is almost like area exept volume is used to measure the space in a 3-dimensional object. volume is length x width x height l x w x h = volume. so for example: if there is a rectangular cube with the length of 3cm, the width of 7cm and the height of 9cm, this would be the formula of how to get the volume: V=l x w x h V=3 x 7 x 9 V= 189 cm cubed

what is area? how do you calculate area? Area is the surface of a flat object. If you want the area of a table measure its length (longest side) and its width (narrowest side) then multiply length and width l x w = Area. for example if you want to get the area of a rectangle that has length of 5cm and a wight of 4 cm, this is what you do:

A = length x width A = 5 x 4 A = 20 cm squared

What is Volume? How do you calculate it? Posted by: Partykala Volume is like Area. The only thing is that area is length x width volume is length x width x height. For example if there is a cube with the length of 4cm the width of 6cm and the height of 10cm you would do this. V= length x width x height V= 4x6x10 V= 240cm cubed

What is Area? How do you calculate that? Posted by: Partykala Area is length x width. For example if there is a square with 4cm as length and 3cm as the width you would do this. A= length x width A= 4x3 A=12cm squared
