"hello students welcome to leader q a
video session
i am saf your math tutor question for
today is
each edge of the cube is increased by 50
find the percentage increase in the
surface area of the queue
let the edge of the queue be a
now surface area of the cube having h a
can be given by
six a square
that is six into side square
let this name as equation number one
as given a new edge after increasing the
at
fifty percent we get here
the increase in the edge is 50 by 50 so
let the increase in edge by 50 d
that is 50 percent of the initial
that is initial edge was a plus
50 percent of a that is 50 into
a divided by 100
and that is
3a upon 2.
now the surface area of the cube having
a h3
upon 2 can be given by
6 into side square at the side is 3a
upon
2 holes square side this is the side
square
now this will give you surface area
which is equal to 27 by 2
a square
now we have to find the increase in the
surface area
so increase in the surface area can be
given by
27 by 2 a square
minus 6 a
square this is taken from this 1 and 2
equations
so you have to subtract the initial
surface area from after surface area
after the increase that is 27 a square
minus 6
a square and this will give you
15 by 2 a square
now it is asked in the question to find
the percentage increase
so here we have to convert this into
percentage so percentage increase
in surface area
will be equal to 15 by 2
a square
divided by
6 a square into hundred
so here six a square was the initial
surface area
we divide this increase by our total
initial surface area and multiplied by
hundred to find the percentage
so you will get
percentage increase
the same thing that is equal to
15 upon 12 into 100
and that is 125 percent
so finally that is our
percentage increase in the surface area
of a cube
which is 125 percent
so if you have got any doubt you can
drop it down in our comment section
and subscribe to liro for more such
interesting q a thank you
for watching"
