A cube has a volume of 128 cm*.It is ofa divided into 8 equal cubes. Then the ratio of an edge of a smaller cube to an edge of the original cube is.

The volume of a cube (in cubic centimeters), whose total surface area is 384 square centimeters, is

The volume(in proper units) of the cone with r as the radius of the circular base and having height h is

If n is the maximum number of solid cubes with an edge of length 0.2 cm that can be put in a box whose dimensions are 1 cm x 1 cm x 4cm then n =

The lengths of the sides of a right angled triangle are in the ratio 3:4. The area of the triangle is 726 square units. Then the length of the hypotenuse (in proper units) is

The ratio of the radii of twocircular ars A and is 2:3 andthatof their heights is 5:3. If the volumeofthe cylinder B is 27 m3, then the volumeofthe cylinder A in cubic meters is.
