Area is the number of square units needed to cover a figure. To find the area of a rectangle, count the number of square units or use a formula.

Multiply the length (l) by the width (w) to find the area (A) of a rectangle.

AREA = LENGTH X WIDTH

The volume of a rectangular prism can be found by counting the number of cubic units or by using a formula. The formula for finding the volume of a rectangular prism is V = l x w x h.

                                               Volume is the number of cubic units needed to fill a 3D figure. The volume of a rectangular prism can be found by counting the

number of cubic units or by using a formula. Multiply the length (l) by the width (w) by the height (h) to find the volume (V) of a rectangle.

VOLUME = LENGTH X WIDTH X HEIGHT

Surface area is the sum of the areas of all the faces of the solid figure. Since opposite faces of rectangles or cubes have the same area,

you can also multiply each area by 2 and then find the sum of the areas of the faces.

The Surface area of a rectangular prism can be found by adding the area of all sides. Multiply the length (l) by the width (w) times 2 plus

the length (l) by the height (h) times 2 plus the width (w) by the height (h) times 2 to find the surface area (SA) of a rectangle.

SURFACE AREA = 2LW + 2LH + 2WH
