"hello and welcome my dear students
i am rishabh the match uteron leader and
i'm here
the new question it says find the
surface area
and the volume of a cube whose one edge
is seven centimeter
so without wasting much time let's have
a look at the solution
it is given that
edge
of a cube
is equal to 7 centimeter and we are
supposed to find out the surface area
and the volume we know that the surface
area
is equals to surface area of
q
is equal to 6 into side square
and we are being given the age of a cube
as 7 so we'll substitute the value
6 into 7 square is nothing but 294
centimeter square
and now we are supposed to find out the
volume so volume
of a cube is equal to
side q and we have been given the side
as 7 so we'll substitute the value so we
get 7 cube
which is nothing but equal to 7 into 7
into 7
which is equals to 343
centimeter cube so i hope
