Rectangles are two-dimensional and you've given us three dimensions, so we'll assume it's some kind of rectangular prism.
2 x 12 x 10 = 240
2 x 12 x 8 = 192
2 x 10 x 8 = 160
240 + 192 + 160 = 592 square cm
multiply length and width,then width and height,then height and width then add your answers together the double it.
A rectangle is a two dimensional object: height, width and length are three dimensions.
length is base and height is width
A rectangle has only two dimensions, for example, length and width. The longest side is usually called the length, the other side, the width.
A rectangle has only two dimensions, for example, length and width. If you multiply that, you get the area. A rectangular box has a length, width, and height. If you multiply all three, you get the volume.
Length x Width x Height = surface area
multiply length and width,then width and height,then height and width then add your answers together the double it.
A rectangle is a two dimensional object: height, width and length are three dimensions.
length is base and height is width
Divide the width by the length: width -------- height
The surface area of a cylinder can be derived from the area of rectangle. If you 'unroll' a cylinder you have a shape of a rectangle, similar to a sheet of paper. The width of the rectangle will be the height of the cylinder and the length of the rectangle will be the circumference of the cylinder end.So, Area = length * widthwhere, width = height of cylinder & length = circumference of cylinder end = PI*(Diameter of cylinder)Therefore,surface area of a cylinder = (PI)*(diameter of cylinder)*(height of cylinder)Hope that helps!

Volume
Length and Width (or Height)
length x width x height or length x breadth x height
multiply length times height times width
