Length x Width x Height = surface area
For a cuboid (a 3D rectangle) of width W, height H and depth D, the surface area is: (WH + WD + HD) x 2.
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!
length times width
It is one surface on a rectangle.
Rectangle
rectangle
The surface area is L*B where L is the length of the rectangle and B is the breadth.
Its surface area.
Surface area of a rectangle is length times width
Surface area = length*width in square units
Multiply the length by the width. If the rectangle is a square the two dimensions will be the same
You need two dimensions to calculate the area of a rectangle. Area = length multiplied by width.
Length x Width x Height = surface area
Surface area of rectangle: 15 times 8 = 120 square inches
actually surface area is always of 3 -d figures not for 2 d figures. area of rectangle= length x breadth.. remember never use surface area term for 2d figures. :)
Rectangle Surface Area: L X W X 6 (the number of sides)
