1- Area of a triangle = (half) x base x height
2- Area of the square = side length x side length
3- Area of a rectangle = Length x Width
4- Area of a parallelogram = Length Base x Height
5- The area of the trapezoid = (half) x the sum of the lengths of its parallel bases x the height
6- The area of the circle = π × 2
7- The area of the rhombus = length base x height
8- Surface area of a prism = the sum of the areas of its faces + the sum of the areas of the two bases
9- The lateral area of the prism = circumference of the base × height
10- The lateral area of the cylinder = circumference of the base x height = 2 squares π ×
11- The total area of the cylinder = the lateral area + the sum of the areas of the two bases
= 2 π × ع + 2 π × 2
12- The lateral area of a right cone = π ×
13- Total area of a right cone = lateral area + base area
= π × n ل + π × 2
14- Area of the circular sector = (H \ 360) x area of the circle
15- Lateral area of the right pyramid = (half) x perimeter of the base of the pyramid x its lateral height
= (half) * length of the base of the triangle * height of the triangle * number of triangles
16- Surface area of the semicircle = 2 (area of the circle) = 2 π × m2
17- The surface area of the sphere = 2 (2 π × m2) = 4 π × 2
18-The area of one face of a cube = length of the letter x itself
19- Total cubic area = area of one face x 6
20- Lateral area of a cuboid = perimeter of the base x height
21- Total area of a cuboid = lateral area + area of the bases

« volumes »
1- Volume of a cube = length x width x height
2- Volume of a cuboid = length x width x height
3- Volume of prism = base area x height
4- Volume of the pyramid = (1/3) the area of the base x the height
5- The volume of the ball = (2/3) x (π x m2) x 2 m = (4/3) π x m3
6- Volume of a right circular cylinder = base area x height = π m2 x p
