A solid metallic cylinder of base radius 3 cm and height 5 cm is melted to form cones, each of height 1 cm and base radius 1 mm. The number of cones is
The base of a right prism is a trapezium whose lengths of two parallel sides are 10 cm and 6 cm and distance between them is 5 cm. If the height of the prism is 8 cm, its volume is:
300 cm cube
300.5 cm cube
320 cm cube
The base of a solid right prism is a triangle whose sides are 9 cm, 12 cm, and 15 cm. The height of the prism is 5 cm. Then, the total surface area of the prism is
) 180 cm square
288 cm square
270 cm square
Area of the base of a pyramid is 57 sq. cm. and height is 10 cm, then its volume in cm cube, is
The base of a right prism is a trapezium. The lengths of the parallel sides are 8 cm and 14 cm and the distance between the parallel sides is 8 cm. If the volume of the prism is 1056 cm cube, then the height of the prism is
The base of a right pyramid is a square of side 16 cm long. If its height be 15 cm, then the area of the lateral surface in square centimeter is:
The height of a right prism with a square base is 15 cm. If the area of the total surface of the prism is 608 sq. cm, its volume is
910 cm cube
920 cm cube
960 cm cube
980 cm cube
If the radius of a cylinder is increased by 25% and its height remains unchanged, then find the per cent increase in volume.
