1. Volume of the cube = a3 cubic units
2. Surface Area = 6a2 square units
3. Diagonal = v 3 a units
Cuboid :
Let l be the length, b be the breadth and h be the height of a cuboid. Then
1. Volume = lbh cu units
2. Surface Area = 2(lb+bh+lh) sq units
3. Diagonal = v (l2+b2+h2)
Cylinder :
Let radius of the base be r and height of the cylinder be h. Then,
1. Volume = ?r2h cu units
2. Curved Surface Area = 2?rh sq units
3. Total Surface Area = 2?rh + 2?r2 sq units
Cone :
Let r be the radius of base, h be the height, and l be the slant height of the cone. Then,
