So, according to the question, first of all we will write the given part, okay? so, we have been given that volume of the whole box, let us say it as v, okay? so, it is 0 .5 meter cube.
00:12
Okay? so, now we will let here, let the dimension, let the dimension of rectangular base, of rectangular, rectangular base, okay? rectangular base is x and height of box is y.
00:40
Height of box is y, okay? so, now if we write the volume, it will be x multiplied by x multiplied by y, okay? so, we can write it as x square y.
00:53
And according to the question, the volume is 0 .5, okay? so, now if we find the value of y here, it will be 0 .5 upon x square.
01:03
This is our equation first.
01:05
Now, we have to find the surface area.
01:07
So, the whole surface area, let us say it, okay? s a.
01:14
So, the surface area will be area of box, area of box, that means the base here, okay? plus area of the rest four sides, area of four sides.
01:29
So, if we write the area of box, it has the dimension x, okay? so, its area will be x multiplied by x plus the area of four sides, four multiplied by area of one side will be x multiplied by y, because it is rectangular, okay? so, x multiplied by y...
