*3-D figure questions for tier-2*

**Kp- 13: A godown building is in the form as shown in the figure given below. The vertical cross-section parallel to the width side of the building is a rectangle 7 m × 3 m, mounted by a semi-circle of radius 3.5 m. The inner measurements of the cubical portion of the building are 10 m × 7 m × 3 m. Find the volume**

*of the godown and the total interior surface area excluding the floor (base).*

*(Take **pi** **= 22/7)*

**Kp-14: A cylinder is within the cube touching all the vertical faces. A cone is inside the cylinder. If their heights are same with the same base, find the ratio of their volumes?**

**Kp-15: The length of an edge of a cube is 24 cm. It is cut by a plane into a pyramid in such a way that its three coterminous edges remain half of their original length. Find the volume of the pyramid?**

**Kp-16: An iron pillar has some part in the form of a right circular cylinder and remaining in the form of a right circular cone. The radius of the base of each of cone and cylinder is 8 cm. The cylindrical part is 240 cm high and the conical part is 36 cm high. Find the weight of the pillar if one cubic cm**

*of iron weighs 7.8 grams.*

**Kp-17: A circus tent is cylindrical upto a height of 3 m and conical above it. If the diameter of the base is 105 m and the slant height of the conical part is 53 m, find the total canvas used in making the tent.**

**Kp-18: A tent is of the shape of a right circular cylinder upto a height of 3 metres and then becomes a right circular cone with a maximum height of 13.5 metres above the ground. Calculate the cost **

*of painting the inner side of the tent at the rate of Rs 2 per square metre, if the radius of the base is 14 metres.*

**Kp-19: The interior of a building is in the form of a right circular cylinder of diameter 4.2 m and height 4 m surmounted by a cone. The vertical height of cone is 2.1 m. Find the outer surface area and volume of the building.**

**Kp-20: The interior of a building is in the form of cylinder of diameter 4.3 m and height 3.8 m, surmounted by a cone whose vertical angle is a right angle. Find the area of the surface and the volume of the building.**

*(Take **** **= 22/7)*
