Question

please answer my two questions

Answer 1

cuboid=3*3*5 [i.e l*b*h]

LCM of 3,5=15

i.e 15cm is the dimension of the final cube.

therefore cuboid required across length=15/3=5

similarly, across breadth=15/3=5

similarly, across height=15/5=3

Therefore total no of cube is 75!







2-----
Area of square field = 5184m^2
Square root of 5184 = 72m 
Therefore perimeter of square field = 4 * 72 = 288m
Rectangular field.
Breadth = x
Length = 2x
Perimeter = 2*length + 2*breadth
= 2(2x) + 2(x)
= 6x
Perimeter of rect field = Perimeter of square field.
6x = 288m
x = 48m
Breadth of rectangular field = 48m
Length of rectangular field = 96m.
Hope this helps.
