SURFACE AREA AND VOLUME

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

The surface area of a cube whose edge equals to 3cm is:

• 62 sq.cm

• 30 sq.cm

• 54 sq.cm

• 90 sq.cm

If the radius of a cylinder is 4 cm and height is 10 cm, then the total surface area of a cylinder is:

• 440 sq.cm

• 352 sq.cm.

• 400 sq.cm

• 412 sq.cm

The curved surface area of a right circular cylinder of height 14 cm is 88 sq cm. The diameter of the base is:

• 2 cm

• 3 cm

• 4 cm

The surface area of a sphere of radius 14 cm is:

• 1386 sq.cm

• 1400 sq.cm

• 2464 sq.cm

• 2000 sq.cm

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:

• 1177 sq.cm

• 1222.77 sq.cm

• 1244.57 sq.cm

The total outside surface area of an open box of dimension 10 cm x 8 cm x 2.5 cm in sq. cm is:

• 50

• 90

• 170

• 250

In a cuboid, all the faces are:

• squares

The diameter of the base of a cone is 10.5 cm, and its slant height is 10 cm. The curved surface area is:

• 150 sq.cm

• 165 sq.cm

• 177 sq.cm

• 180 sq.cm

The Curved surface area of a right circular cylinder is 4.4 sq.cm. The radius of the base is 0.7 cm. The height of the cylinder will be:

• 2 cm

• 3 cm

• 1 cm

• 1.5 cm
