Answer 1

Area Of A =6x(side)^2= 6x100=600cm^2
As in case of a cube, Lateral Surface Area consists of area of four of the cube sides.

therefore area of b would be 4x(side)^2 =
$4 \times {8}^{2}$
=4x64
=256cm^2

Answer 2

Answer:

Area Of A =6x(side)^2= 6x100=600cm^2

As in case of a cube, Lateral Surface Area consists of area of four of the cube sides.

therefore area of b would be 4x(side)^2 =

4 \times {8}^{2}4×82

=4x64

=256cm^2
