Question

each face of cube has perimeter to 32 cm find its s. a

Answer 1

Since perimeter of each face of cube = 4* edge

=) 4* edge = 32cm

=) edge = 32/4 = 8cm.

For tsa = 6* edge^2 and csa = 4* edge ^2.

Hope it's helpful to u.

Answer 2

each face of the cube=a square
therefore, if the perimeter of the square=32
then side=?
perimeter of the square=4*side
32=4*side
32/4=side
8=side
therefore,side of the cube=8cm
the surface area=6*(side square)
                           =6*(8*8)
  =6*64
=348cm

hope it helps..
