Lateral surface area of a cube is ________

• 2(l+b)h

• 2(lb+bh+hl)

If slant height of the cone is 21 cm and the diameter of the base is 24 cm. The total surface area of a cone is:

• 1200.77 sq.cm

• 1177 sq.cm

• 1222.77 sq.cm

• 1244.57 sq.cm

The formula to find the surface area of a cuboid of length (l), breadth (b) and height (h) is:

• lb+bh+hl

• 2(lb+bh+hl)

• 2(lbh)

• lbh/2
