Surface area of a cube whose side is $$\dfrac{1}{2}\ cm$$ is:

A cylindrical bucket of height 36 cm and radius 21 cm is filled with sand. The bucket is emptied on the ground and a conical heap of sand is formed. The height of the conical heap is 12 cm. The radius of the heap at the base is

In 

$$\Delta$$ LMN 






































such that $$LP = 2 cm   and   PM = 6 cm $$.
 Also $$MN = 20 cm$$.
Then the ratio of ar(trapezium PQNM) to ar($$\Delta$$LPQ) 



is:

Sixteen cylindrical cans, each with a radius of 1 unit, are placed inside a cardboard box four in a row. If the cans touch the adjacent cans and or the walls of the box, then which of the following could be the interior area of the bottom of the box is square units?

$$12$$ litres of water are poured into an aquarium of dimensions $$50$$cm length, $$30$$cm breadth, and $$40$$cm height. How high (in cm) will the water rise?($$1$$ litre$$=1000cm^3$$)

The diagram shows the net of a right cylinder. Find the volume of the cylinder, in cm$$^3$$

In the figure ABCD is a trapezium in which AB = 15 cm. DC = 9 cm and DE = 8 cm, then the area of ABCD is 

A water tank has a capacity of $$10,000$$ litre. Its value in $$m ^ { 3 }$$ is

Find the sum of the lengths of the parallel sides of a trapezium whose altitude is 11 cm and whose area is $$0.55m^2$$

In $$\Delta ABC,D,E,F$$ are the mid points of sides BC, CA and AB respectively. If $$ar\left( {ABC} \right) = 16\,\,{cm^2},$$ then $$ar(trapezium\, \,FBCE)=$$
