Practice finding the area of a rectangle. The formula is Area = length × width.
Multiply length by width: Area = length × width. A rectangle 8 long and 5 wide has an area of 8 × 5 = 40 square units.
Area is measured in square units — square inches, square feet, square centimeters, and so on.
Cubles kits are geometry in your hands: nets, faces, edges and vertices that fold and click into a poseable 3D character. No scissors, no glue, about 15 minutes.
