Rectangle :

6- – Circle:
Circumference = Diameter x
or
2 x Raduis x
Diameter = Circumference ÷ , Raduis = circumference ÷ ÷ 2
Area =
2Raduis
=
Diameter = 2 x
7 – Cube :
Lateral surface area = Area of one face x 4
Or = Side x side x 4
Area of one face = LSA ÷ 4
Total surface area = Area of one face x 6
Or Side x side x 6
Area of one face = TSA ÷ 6
Volume = side x side x side
8- Cuboid :
Lateral surface area =Perimeter of the base x height
=( L+W)x2xh
46
Total surface area = Lateral surface area + sum of the two areas of the
base
= LSA + 2X base areas
(L +W ) X 2 X h + (2 x L x W )
Volume = L x W x H
