Answer: In that case 392 × 7 = 2 × 2 × 2 × 7 × 7 × 7 = 2744 which is a perfect cube. Hence the smallest natural number by which 392 should be multiplied to make a perfect cube is 7.

food provided for for 1500 soldiers for 48 days
if 1 soldier eat 1 roti in 1 day 1500 eat 1500 rotis in 1 day
and for 48 days 1500 × 48 = 72000 rotis provided
till 13 days there are only 1500 soldiers
that means 1500 × 13 = 19500
the remaining food after 13 days is 52500
assume that x number of soldiers joined
that means the remaining food is for 1500 + x soldiers
52500/1500 + x = 25
52500 = 37500 + 25x
25x = 15000
x = 600

In Geometry, a square is a two-dimensional plane figure with four equal sides and all the four angles are equal to 90 degrees. The properties of rectangle are somewhat similar to a square, but the difference between the two is, a rectangle has only its opposite sides equal. Therefore, a rectangle is called a square only if all its four sides are of equal length. Square Number of sides = 4 Number of vertices = 4 Area = Side2 Perimeter = 4(Side) The other properties of the square such as area and perimeter also differ from that of a rectangle. Let us learn here in detail, what is a square and its properties along with solved examples. Definition Square is a regular quadrilateral, which has all the four sides of equal length and all four angles are also equal. The angles of the square are at right-angle or equal to 90-degrees. Also, the diagonals of the square are equal and bisect each other at 90 degrees. A square can also be defined as a rectangle where two opposite sides have equal length. The above figure represents a square where all the sides are equal and each angle equals 90 degrees. Just like a rectangle, we can also consider a rhombus (which is also a convex quadrilateral and has all four sides equal), as a square, if it has a right vertex angle. In the same way, a parallelogram with all its two adjacent equal sides and one right vertex angle is a square. Properties of a Square The most important properties of a square are listed below: All four interior angles are equal to 90° All four sides of the square are congruent or equal to each other The opposite sides of the square are parallel to each other The diagonals of the square bisect each other at 90° The two diagonals of the square are equal to each other The square has 4 vertices and 4 sides The diagonal of the square divide it into two similar isosceles triangles The length of diagonals is greater than the sides of the square
