Here a, b and c are the areas of the adjacent sides of a cuboid. If the cuboid has its sides x, y and z then N=x*y*z and N^2 = (x*y*z)^2.

If blue rectangle area is equal to the sum of 3 squares areas combined as in image, what is relation between a,b,c & d?

A cuboid of dimension 7 cm * y cm * 15 cm is given. Find the minimum value of y so that at least two cones of maximum volume having some dimensions and a height of 15 cm, can be cut from this solid.

Babu has a cuboid with dimension - a x b x c and he also has 3 cubes with side lengths a, b and c respectively. What is the relation between cuboid volume and the volume of cubes?

If

a+b=8, a+c=13, b+d=8, c-d=6

Then

a, b, c, d = ??
